--- Comment #7 from m.cencora at gmail dot com --- Created attachment 57921 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57921&action=edit Full "std" module FYI if you want to stress test the modules impl w.r.t. similar issues, here is std.cpp for almost whole Standard Library. Some code is disabled (with 'bug' comment). This is based on semi-preprocessed and hand-adjusted 'std' module code from libc++
