--- Comment #4 from Paul Floyd <pjfl...@wanadoo.fr> --- I've tried a GCC 12 build of Valgrind with both a GCC 4.8.2 and GCC 12 built versions of signal2 and they both crash. So it's not a change in the compilation of the testcase that's the problem. Next, in gdb I get the segfault here in syswrap-solaris.c: │ 534 /* Clear uc->vki_uc_signo. This slot is used by the signal machinery to │ 535 store a signal number. */ │ 536 VKI_UC_SIGNO(uc) = 0; │ 537 │ 538 /* Sigmask */ │ > 539 uc->uc_sigmask = tst->sig_mask; │ 540 VG_TRACK(post_mem_write, part, tid, (Addr)&uc->uc_sigmask, │ 541 sizeof(uc->uc_sigmask)); If I compile syswrap-solaris.c without -O2 then the signal2 test works. And in fact the problem exists with -O1 and not with -O0. -- You are receiving this mail because: You are watching all bug changes.
