Extended Description

Bootstrap is broken on linux i686. The stage2 compiler segfaults. I have reduced the problem to wrong code being produced for tree-cfg.c.

The attached tree-cfg.bc is correct. It was produced with -O0. Passing it by "opt -std-compile-opts" produces an invalid output.

To reproduce the bug I am manually linking cc1. If someone wants I can upload the ".o" files.

Rafael, is it on TOT? At least, I can confirm, that bootstrap was fine on x86/linux 2-3 weeks ago.

This has been fixed. I just recompiled the attached testcase for this bug and relinked. I will try a full bootstrap on Friday.

I'm doing full bootstrap and it should finish soon.
