Subject: [Bug bootstrap/17591] Ada bootstrap SEGV in stage2 on osint.adb, no SEGV when -fno-ivopts
Date: Wed, 22 Sep 2004 21:24:00 -0000 [thread overview]

I deactivated ivopts with the following patch:

It cured the problem, and also fixed the following
ACATS tests on x86: c37003a c43204e c48009b cc3224a cxaa010
The 19 remaining ACATS failure are identical on x86 and x86_64
and do not seem related to ivopts.
Zdenek, what information I can provide would be helpful to you on this issue?
I can try reducing some of the five tests above, here are their exact failure mode:
