It is possible that there is a bug in the code itself, but nothing
above
points to my created code.
Any suggestions? Or is this a bug?
Are you using C extensions in your code? If so I would suspect them for
corrupting python. I think you can get into gdb inside the core file with coredumpctl debug.
The python code calls a shared object library that is written in C. But why does this core dump only happen in F39 (python 3.12) and not with F38 (python 3.11)?
There were some big changes in 3.12 (driven by the need to support Fortran on Windows and macOS by replacing very old gfortran version with flang-new). I havrn't had time to look at what is being used in linux, but you could get a quick overview from ldd. See: < https://discuss.python.org/t/why-scipy-builds-for-python-3-12-on-windows-are...
There is also new build system, so a lot of work getting everything working in 3.12. Meanwhile you can run 3.11 stuff using python environments.
