| Summary | 0000929: midi assign cancel crash | ||||
| Description | when I try to automate a mixerfader per Ctrl + middlebutton and ardour is not via jack connected to my mpu401-midiport and I therefor cancel and try a second time ardour will crash. ardour will also crash if I try to automate once and cancel it and afterwards turn a knob on my midicontroller. I gues it will crash whenever I cancel the MIDI-automation (operate MIDI controll now) process and then come across with midi again. on the console it prints out "Speicherzugriffsfehler". means someting like memoryaccessfailur lukas | ||||
| Additional Information | 2.6.11-gentoo alsa 1.0.8 jack 0.99 ardour beta28 (is not choosable in mantis under Product-Version!) | ||||

I see the same bug. Ardour beta28. To reproduce... Create a new session. Create a mono track. Add a plugin as an insert on that track. Open the plugin's window. Ctrl+middle click on a slider. Close the 'Operate midi controller now' window without touching any midi controls. Ctrl+middle click on *the same* slider. Ardour segfaults. Notes: If you select a different slider the second time, there is no problem. |

any chance of a gdb backtrace from either of you? |
|
|
Sorry I can't do that but I'll ask my brother and if he's able I'll let you know. |

Okay. This is with the cvs tarball... Ardour gtk 0.583.0 libardour 0.883.0 I'm not quite sure how to use gdb, but this is what it displayed when doing the midi assign crash: Loading session /mnt/hdd3/capture/swim/live using snapshot live [New Thread 65541 (LWP 7739)] [New Thread 81926 (LWP 7740)] [New Thread 98311 (LWP 7741)] Program received signal SIGSEGV, Segmentation fault.

Is this still an issue with the latest Ardour-2? |
|

i deem this solved. the code has changed substantively, and the steps philicorda outlined to reproduce do not cause any problems. |
