--- Comment #2 from Dev Dude <devdude2 at hotmail dot com> --- Just to clarify the initial comment if it is unclear: It's unclear how to compile C++ standard headers. If I use the script below to try to build all the standard c++ headers, I see the "random" header errors and the "execution" header crashes compiler (see output in original post). But if I re-run the script, random and execution compile successfully. The crash in "execution" is a compiler bug or an incorrect assertion. But that the process fails then works on re-run, seems to be a bug to in that the header build is order dependent or sometning when it probably shouldn't be To see this, save the script in the original comment as make_gcc_headers.sh then do . make_gcc_headers.sh then . make_gcc_headers execution random I hope this clarifies things and how to reproduce this problem if it was unclear before. Thanks Oh one other thing, I think I accidentally cut the related errors from using the collective headers after they successfully compile on second pass. I don't think this adds much, as it may go away once you fix the other problems, but in case it helps here those errors are too: [build] In module imported at /home/gm/projects/chess/src/libutil/util.cpp:49:1: [build] /home/gm/projects/chess/src/libutil/util.cpp: In substitution of ‘template<class> constexpr std::__cxx11::basic_string<char>::basic_string(const char*, const std::allocator<char>&) [with <template-parameter-1-1> = std::allocator<char>]’: [build] /home/gm/projects/chess/src/libutil/util.cpp:88:18: required from here [build] 88 | mypath = pathbuf; [build] | ^~~~~~~ [build] /home/gm/local/install-mygcc/include/c++/15.0.0/filesystem: error: failed to read compiled module cluster 1499: Bad file data [build] /home/gm/local/install-mygcc/include/c++/15.0.0/filesystem: note: compiled module file is ‘gcm.cache/./home/gm/local/install-mygcc/include/c++/15.0.0/filesystem.gcm’ [build] /home/gm/projects/chess/src/libutil/util.cpp:88:18: fatal error: failed to load pendings for ‘std::__cxx11::basic_string’ [build] 88 | mypath = pathbuf; [build] | ^~~~~~~ But the stack dump showing and compiler crash related to __concurrence_lock_error in the original post is the main thing in this post relating to gcc. But to see it, you'll have to run the script that I gave.
