I'm seeing some crashes of code using OpenMP build with clang 20.1.7 inside containers on a Linux box:
`Assertion failure at z_Linux_util.cpp(2108): file != NULL`
Looking at the code in question, this error is generated here:
https://github.com/llvm/llvm-project/blob/main/openmp/runtime/src/z_Linux_util.cpp#L2121-L2125
if `/proc/<pid>/maps` can't be opened.
I'm not sure yet how exactly this is triggered (given the container in question does mount /proc inside it); I suspect it may happen when the conatiner is set up (decompressing the filesystem image for the container is parallelized -> openmp code is called -- but /proc is only mounted inside the container after the filesystem image is ready).
