--- Comment #4 from Andy Lutomirski <luto at mit dot edu> 2011-12-15 00:00:18 UTC --- Created attachment 26095 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26095 Partially reduced test case This is reduced by a combination of fiddling by hand and automated reduction. It's still not pretty, but it's considerably shorter than the original version. I still haven't been able to reproduce the bug from scratch.
