Btw, I have found this is atf's documantation: atf_tc_expect_signal(SIGSEGV, "reaseon"), with this, we could mark the specific test case could "fail" / or expect to coredump. > >> things. > > things. -> things [for FreeBSD]. > >> If somebody run the test suite for libc, she would immediately note >> another failing test for the stack protector, which is similar to the >> gettimeofday nonsense. > > Perhaps, but that's assuming that NetBSD implemented gettimeofday in > userland, which is doesn't. > > I agree that this is less applicable for FreeBSD than NetBSD.
