I think this would also be a solution. Would this then be included in a fut= ure GCC 13.2? Took quite a while until I figured out the reason for the segfaul= t. Just for completeness sake. I also posted it on one of the brew repositories for GCC. Probably this could be patched on macOS also for GCC 13.1. https://github.com/iains/gcc-13-branch/issues/6=
