I develop and build the DeepSkyStacker application on an M4 Mac Mini. A user reports that with a given set of data files and application settings, that it crashes on his M4 MAX.

He sent me his data files, and I can't provoke a crash on my M4.

He also sent an App Crash report file which I attach.

Any insight into the likely cause of the problem will be appreciated (yes, I know it is a segfault in code called from Avx256Stacking::pixelPartitioning - probably a lambda ...).

Does no-one have any suggestions? I guess it is possible that this is an M4 MAX silicon problem?

Are you subdividing some work between different thread? The M4 Max has more cores, and it might expose some multi-threaded issues that aren't visible with fewer cores.

Or there is some random out of bounds writing somewhere that for some random reason doesn't cause a crash on your Mac.

Try to run it address sanitizer first, and then with thread sanitizer.
