It seems reasonable to me for try { X } catch... to mean X when
-fno-exceptions. We don't need to error except on throw.
It seems unreasonable to me that gcc would silently modify

I think that was a mistake. He was just trying to confirm the PR, and probably
meant to set it to WAITING as opposed to ASSIGNED. I saw your emails to
gcc-patches. If you could commit the change, that'd be awesome.

Try turning on warnings. That is -Wsquence-points. The above is
specified behavior
The following example dumps a core if compiled with -march=i586 -fPIC:
#include stdint.h
int main(void)
{
static uint64_t volatile s_u64;
__sync_bool_compare_and_swap(s_u64, 0, 0);
}
The reason is that %ebx will be used as pointer for the memory variable.
I can reproduce this bug so far
