The problem reproduces, so it appears to be independent of the compiler used for stage 1. Should I test with individual options that make up -O3 to try and narrow it down? I'll start doing that while I wait for further debugging instructions. You can track me down on freenode IRC as syke, if need be. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42628
