Access violation on Windows
Describe the bug When handling frame packets from the camera an access violation occurs in aravis. As long as packets are blocked by the firewall nothing happens, but as soon as it is turned off the error occurs.
To Reproduce I build the library using the current MSYS2 version.
Here the meson logs:

Expected behavior A version I build using version 0.8.21 is working fine (~15.03.2022). But this build was also based on an older version of MSYS2 and the dependend libraries like glib.
Camera description: Self build in memory camera. It is working fine with old aravis and Pleora eBus Player, so I think this is not causing the issue.
Platform description:
- Aravis version: Current state of the main branch
- OS: Windows 10 21H2
- Hardware: Dell Laptop / Intel i9-9980HK
Additional context Here the stack trace from Visual Studio:
libaravis-0.8-0.dll!00007fff45aff5b4() unknown (I assume it to be _process_packet) libaravis-0.8-0.dll!00007fff45b00029() unknown (I assume it to be _loop) libglib-2.0-0.dll!00007fff45866ce1() unknown libglib-2.0-0.dll!00007fff458952b7() unknown msvcrt.dll!00007ff859e6af5a() unknown msvcrt.dll!00007ff859e6b02c() unknown kernel32.dll!00007ff858d27034() unknown ntdll.dll!00007ff859fa2651() unknown
I assume that error is caused in the _process_packet method (arvgvstream.c), but I cannot debug the code.
Side question: Is there a way to generate a .pdb file on windows so that debugging would be possible in Visual Studio?

Try to change the buildtype to debugoptimized:
meson configure -Dbuildtype=debugoptimized
I also tried 0.8.22 last week, and it crashed in arv_camera_start_acquisition (multi example). 0.8.20 did not,. (camera: AVT manta 125g).
Not just own code, arv-camera-test-0.8.exe also crashes.
If you are building aravis using the git repository, could you try to find the faulty commit using git bissect ?
I tried my luck with msys and built aravis 8.20, 8.21 and 8.22 for x86_64-mingw64 and 21 and 22 have segmentation fault in arv-camera-test and 20 not, all built with the same msys environment.
If you have detailed instructions for the bissecting, I'll give it a go

Any updates regarding this? I have the same segmentation fault on windows 11 on Aravis version 8.21 and 8.22, but not on 8.20.
Hi @mikkellars
I don't have a development environment on Windows, so, as I said to @marcovtje , finding the commit that introduced the issue using git bisect would help. It is quite straightforward to use: https://git-scm.com/docs/git-bisect
Long time, no news. I'm closing this issue. Don't hesitate to reopen when you have the requested informations.
Cheers.
