Description John David Anglin 2005-01-08 18:39:22 UTC 
The tests have failed since inception at -O2.  They also started failing
at -O1 between Thu Sep 16 02:02:25 UTC and Sun Sep 26 19:50:51 UTC 2004.
Comment 1 Andrew Pinski 2005-01-08 19:06:27 UTC 
Can you manually test this test in 3.4.x as I think this might be a regression.  (well -O1 is though).

Yes, with 3.4.3, both tests pass at -O1 and abort at -O2.  The failure
in -1 at -O2 with 3.4.3 is in testE:

(gdb) bt
#0  0x800003fffef81700 in abort () from /lib/pa20_64/libc.2
#1  0x4000000000006828 in testE ()
