Comment 1 Andrew Haley 2004-09-27 10:12:42 UTC 
See http://gcc.gnu.org/ml/gcc-regression/2004-09/msg00184.html.

FAIL: Array_3 execution - source compiled test
FAIL: Array_3 -O3 execution - source compiled test
FAIL: Invoke_1 execution - source compiled test
FAIL: Invoke_1 execution - bytecode->native test
FAIL: Invoke_1 -O3 execution - source compiled test
FAIL: Invoke_1 -O3 execution - bytecode->native test

These tests were specially written to test unwinding from SEGV signals.

Comment 3 Andrew Pinski 2004-09-27 12:34:06 UTC 
It works on powerpc-apple-darwin though: <http://gcc.gnu.org/ml/gcc-testresults/2004-09/
msg01185.html> so this might be a target problem.
Comment 4 Andrew Haley 2004-09-27 12:51:59 UTC 
It's i386 specific.  I'm working on a patch now.
