--- Comment #6 from Stas Sergeev <stsp at users dot sourceforge.net> --- I think the fix (of at least 1 problem here) would be to move this line: https://code.woboq.org/gcc/libsanitizer/asan/asan_thread.cc.html#109 upwards, before this: https://code.woboq.org/gcc/libsanitizer/asan/asan_thread.cc.html#103 It will then unpoison stack before playing its sigaltstack games. But I don't know how to test that idea.
