Since kernel 2.6.22.1-27.fc7 (x86 SMP) this test fails because the abort(),
which should never be reached is triggered in funit-breakpoints:
// Generating a trap event ourselves, simulating "bad code". Setup
// a sigsetjump so we can handle it and return from this function
// safely when the signal handler uses longjmp. On some
// architectures the PC isn't incremented on invallid/trapping
// instructions. So this makes sure we skip it when we return.
if (sigsetjmp (env, 1) == 0)
{
send_trap++;
#if defined(__i386__) || defined(__x86_64__)
asm("int3");
#elif defined(__powerpc64__) || defined(__powerpc__)
asm(".long 0x7d821008");
#else
#error unsuported architecture
#endif
abort(); // Should never be reached.
This is most likely related to and depends on a real fix for handling signals
during stepping outlined in bug #4747 (int3 is a somewhat difficult case though,
that probably should be handled independently by special casing since it
generates a SIGTRAP which isn't a rt signal, so it doesn't queue multiple and
you will only get one).
