--- Comment #18 from Stas Sergeev <stsp at users dot sourceforge.net> --- (In reply to Stas Sergeev from comment #5) > And its running on a stack previously > poisoned before pthread_cancel(). And the reason for that is because the glibc in use is the one not built with -fsanitize=address. When it calls its __do_cancel() which has attribute "noreturn", __asan_handle_noreturn() is not being called. Therefore the canceled thread remains with the poison below SP. I believe the glibc re-built with asan would not exhibit the crash. Note: all URLs above where I was pointing to the code, now either are a dead links or point to wrong lines. Its quite a shame that such a bug remains unfixed after a complete explanation was provided, but now that explanation is rotten...
