I am compiling my project with clang-16 which worked fine so far, but now I am getting a segmentation fault from clang itself during compilation:

Segmentation fault

There is no stacktrace or any other further info on where or how this happens so I am a little lost. Compiling with -v (verbose mode) doesn't add any further info except for the exact run command

I would expect clang to throw the stacktrace or other info on this, so I am actually unsure if this is even clang's or potentially ninja's segfault?
