| Steps To Reproduce | Add "ardour4" client in a NSM session Add a Carla host with some cabbage lv2's, do a record ( notes played to carla with seq24 trough a2j midi bridge). Save, quit and open ardour in the NSM session manager. | ||||
| Tags | No tags attached. | ||||
|

I can't reproduce because I have neither Carla nor Cabbage installed and no NSM. Can you reproduce the issue when re-opening ardour without NSM? Would you mind getting a backtrace http://ardour.org/debugging_ardour ? double-free are often indicative of memory corruption, and in many cases those are caused by plugins. If you can reproduce the issue without NSM, how about with `Ardour --disable-plugins`? |

It hangs outside NSM, however not disabling plugins! I uploaded a backtrace from ardour4 --gdb ( and here https://bpaste.net/raw/b8b871c7dd4b ) You're effectively right, gx_amp_stereo.lv2 is faulty there. I'm gonna look with guitarix team. Edit: I created a ticket here https://sourceforge.net/p/guitarix/bugs/32/ |

Ticket on guitarix is updated. I reopen the ticket here with more details I ommited: The bug seems triggered when loading saved parameters in the lv2 plugin. There's a backtrace from a debug build: https://bpaste.net/raw/f1effb3fcd50 and a full log disabling plugins: https://bpaste.net/raw/1608f4fd680a |

probably https://github.com/FFTW/fftw3/issues/16 (causing memory corruption) It's fine when adding plugins one at a time but when loading a session there'll be concurrency issue and undefined behavior. |

Guitarix is rebuilt with ffmpeg instead of fftw3. There's the segfault (bt attached) clicking the save preset button but on certain conditions. Maybe that's a better view of the problem now. I'm gonna look at your issue on fftw for understanding a bit more. Thanks you |

Hello there, I follow back my reply on guitarix's SF >Hello, > >I was unable to reproduce too with or without --convolver-ffmpeg. So i've reinstalled the packaged version from KXStudio, tried again and then it crashed, as I get initially. > >The makefile for that package only configures with --no-faust. I'm gonna ask falktx@ what he think about the bug. > >Thanks you very much sirs, I've learned lot of good things! > >Best regards. > >PS: Can you please close the ticket at SF. Thanks you ! |
