Describe the bug
When built on Debian 11, the executable sneedacity segfaults on launch.

To Reproduce

  1. Install the required packages
  2. Try to run Cmake.
  3. The source tree doesn't have a sneedacity subdirectory, guess we're using .. instead.
  4. Run make
  5. Run bin/Debug/sneedacity
  6. See a "segmentation fault" error

Expected behavior
A clear and concise description of what you expected to happen.

  1. You wouldn't be telling us to refer to ../sneedacity, which doesn't exist once we cd into build.
  2. I have all the dependencies, and all the warnings about how wxWidgets shouldn't be using GTimeVal and all the deprecated declarations shouldn't matter.
  3. The binary doesn't segfault on launch
    Screenshots
    If applicable, add screenshots to help explain your problem.

Additional information (please complete the following information):

  • OS: Debian 11 Bullseye
  • Version: Sneedacity 3.x, I think I cloned it
  • Sound Device: ALSA/PulseAudio on an Intel HD Audio chipset

Additional context
Add any other context about the problem here.

I was able to confirm this bug on a fresh amd64 Debian VM.

It happens inside the function Pa_Initialize() called in the line PaError err = Pa_Initialize(); of the file AudioIO.cpp.
We need to find out why Portaudio is segfaulting.

Add more debug logs. Fix segfault on debian 11 (issue #267) by moving…
9bf36c7 
… ffmpeg init earlier so that when avcodec_register_all() is called by the system's libasound_module_pcm_a52.so, the function pointer declared in FFmpeg.h isn't null. However the fact that system's libraries have dependencies fulfilled by older versions in the repo is very wrong and will cause issues down the line. (#268)

I don't know why the build action hasn't triggered so I'm merging it.

Should be fixed in commit 9bf36c7. Please re-open if the error persists.
