| Summary | 0000802: Ardour crashes on adding a new bus | ||||
| Description | Hi! Always then I try to add a new bus to a project, by right clicking in the editor and choosing to add a new bus. Ardour won't run i gdb on my system (Debian unstable, 500 MHz Celeron, 400 MB RAM), so I can't provide a backtrace. Anything else I can do to help find the problem? Thanks! | ||||

Run the command ulimit -c unlimited, then run ardour from that shell. When ardour segfaults, it will leave a corefile in the directory you ran ardour from. Usually the file is called core.pid, where pid is the pid of ardour when it crashed (core.12345 for example). Run gdb /path/to/ardour core.pid, then 'thread apply all bt' from the prompt |

Hi! Ah, thank you! :) I have not performed such advanced bug hunting before. Now I also noticed that the problem does not occur with a freshly started new session, but in my real-work sessions it always seems to do so. In the Konsole I got the message [2]+ Floating point exception(core dumped) ardour (the [2] referring to ardour as being the second job run, qjackctl is [1]). The backtrace is: Thread 7 (process 11444): #0 0x403c679f in do_sigwait () from /lib/tls/libpthread.so.0 0000001 0x403c672c in sigwait () from /lib/tls/libpthread.so.0 #2 0x0831ece0 in signal_thread () at base.cc:20 #3 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 0000004 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 6 (process 11450): #0 0x406d5fe3 in poll () from /lib/tls/libc.so.6 0000001 0x085e5f5d in ARDOUR::Source::peak_thread_work () #2 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 #3 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 5 (process 11452): #0 0x406d5fe3 in poll () from /lib/tls/libc.so.6 0000001 0x402ba2f1 in jack_stop_freewheel () from /usr/lib/libjack-0.80.0.so.0 #2 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 #3 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 4 (process 11520): #0 0x406d5fe3 in poll () from /lib/tls/libc.so.6 0000001 0x0858a534 in ARDOUR::Session::butler_thread_work () #2 0x0858a4bc in ARDOUR::Session::_butler_thread_work () #3 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 0000004 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 3 (process 11521): #0 0x406d5fe3 in poll () from /lib/tls/libc.so.6 0000001 0x085b7b77 in ARDOUR::Session::midi_thread_work () #2 0x085b7a13 in ARDOUR::Session::_midi_thread_work () #3 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 0000004 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 2 (process 11522): #0 0x406d5fe3 in poll () from /lib/tls/libc.so.6 0000001 0x085b1895 in ARDOUR::Session::feedback_thread_work () #2 0x403c0b63 in start_thread () from /lib/tls/libpthread.so.0 #3 0x406dec4a in clone () from /lib/tls/libc.so.6 Thread 1 (process 11441): #0 0x0859e5f8 in ARDOUR::Session::new_audio_route () 0000001 0x08186680 in ARDOUR_UI::session_add_audio_route () at base.cc:20 #2 0x0818d0ef in ARDOUR_UI::add_route () at base.cc:20 #3 0x08256164 in Editor::edit_controls_button_release () at base.cc:20 0000004 0x08259936 in SigC::ObjectSlot1_<int, _GdkEventButton*, Editor>::callback () at base.cc:20 0000005 0x0816d137 in Gtk::ProxySignal1<int, _GdkEventButton*, Gtk::Widget, _GtkWidget, 18>::gtk_callback () #6 0x084ab93d in gtkmm_marshal_INT__POINTER (object=0x1, func=0x816d120 <Gtk::ProxySignal1<int, _GdkEventButton*, Gtk::Widget, _GtkWidget, 18>::gtk_callback(_GtkObject*, _GdkEventButton*, void*)>, func_data=0x1, args=0x0) at marshal.cc:240 #7 0x401096d5 in gtk_signal_remove_emission_hook () from /usr/lib/libgtk-1.2.so.0 0000008 0x4010898b in gtk_signal_set_funcs () from /usr/lib/libgtk-1.2.so.0 0000009 0x40106134 in gtk_signal_emit () from /usr/lib/libgtk-1.2.so.0 0000010 0x40147748 in gtk_widget_event () from /usr/lib/libgtk-1.2.so.0 0000011 0x400d0a0f in gtk_propagate_event () from /usr/lib/libgtk-1.2.so.0 0000012 0x400cf7d4 in gtk_main_do_event () from /usr/lib/libgtk-1.2.so.0 0000013 0x4018ffd5 in gdk_wm_protocols_filter () from /usr/lib/libgdk-1.2.so.0 0000014 0x08a2fa28 in ??

your backtrace will be infinitely more useful to us if you could first rebuild ardour with gdb debugging enabled. to do this, go to the top of the source tree, type ./configure --enable-debug plus any other arguments you used, and then make (followed by an optional make install). then generate another backtrace as described already. if you are using a binary package, don't worry about this. it would be great if you could try the source release so we can track it down, but i understand that doing so can be very time consuming. |

Hi again! Hope you had a nice Christmas. :) I attached the file buscrash.txt, but I think it looks just the same, even though I got today's nightly CVS and compiled with the option you suggested. (I did not do a new autogen nor did I do a make clean of the previously compiled files.) mkurula@KuruLund:~$ ardour --version Ardour/GTK 0.549.1 running with libardour 0.851.3 Thank you! :) Mikael |

I can confirm that this bug is still around in 0.99. I've reproduced it on two machines with the following steps: 1. Re-open any previously-saved session (even a completely empty one), or create a new session based on an existing template. 2. Choose "Add Track/Buss" from the Session menu. 3. Attempt to create an arbitrary number of busses with an arbitrary channel configuration. 4. Click "OK" I'm consistently met with a crash at this point. If I run Ardour from the console, the only output generated by the attempt to create a buss is "Floating point exception". I'll upload an example session (empty.ardour) which triggers the crash on both of my Ardour-capable machines. I tried to create a backtrace, by following the directions earlier in the discussion (scons DEBUG=yes), but was unsuccessful. My first attempt produced a chain of items like this: 0002582 0x00000015 in ?? () 0002583 0x00110015 in ?? () 0002584 0x00040038 in ?? () 0002585 0x030000c4 in ?? () 0002586 0x00080000 in ?? () I suspected that SCons might have stripped the debugging symbols out of Ardour, so I replaced /usr/bin/strip with an empty shell script, and rebuilt from scratch. Now the output of 'thread apply all bt' is: Thread 7 (process 1273): #0 0x00200246 in ?? () Error accessing memory address 0x0: No such file or directory. Oh well. Let me know if there's anything else I can try - I'm getting tired of using KWrite to create busses in my session documents. ;) |) |)enji |

I believe I've further isolated the bug. It only happens when JACK is started in playback-only mode. Somewhere during the process of creating a buss, Ardour assumes that there is at least one hardware input available. If there are no hardware inputs, Ardour dies. Naturally, I'd still like to see this bug get fixed, but the simple workaround (which isn't really too much of a problem for me, now that I know about it) is to ensure that JACK is started in full-duplex mode. The only reason JACK was running in playback-only mode was because of permission problems with my audio device files. The quick-and-dirty solution, for anyone else who might be having the same problem, is to add something like the following to your local system initialization script (e.g. /etc/rc.d/rc.local on a Slackware machine): chmod a+rw /dev/dsp* /dev/snd/* |) |)enji |

Just tested with 2.0beta7. A year ago, benji guessed right. switch jack to playback only, create a new bus and you get it to crash. |
