Comment 2 Andrew Pinski 2004-09-11 14:18:31 UTC 
I almost think this is a dup of bug 17382, as all four OS's use setjmp/longjmp exceptions.
Comment 3 Andrew Pinski 2004-09-11 22:02:29 UTC 
Confirmed, reduced to:
void __gthread_mutex_lock ();
void
__cxa_free_exception(void *vptr) throw()
{
  __gthread_mutex_lock ();
}
Comment 4 Andrew Pinski 2004-09-11 22:03:57 UTC 
*** Bug 17382 has been marked as a duplicate of this bug. ***
Comment 5 Steven Bosscher 2004-09-11 22:38:46 UTC 
A compiler build with configure --enable-sjlj-exceptions exposes this bug on 
all targets I could try it on.
Comment 6 Steven Bosscher 2004-09-11 23:00:41 UTC 
The problem is in except.c:sjlj_emit_function_exit
Comment 7 Andrew Pinski 2004-09-12 02:43:40 UTC 
The patch in PR 17186 allows me able to bootstrap on i686-pc-openbsd3.1, results will follow soon.
Comment 8 Andrew Pinski 2004-09-12 17:38:50 UTC 
This is fixed now too by RTH's patch.
