--- Comment #2 from Mikael Pettersson <mikpe at it dot uu.se> 2012-03-27 07:42:46 UTC --- Created attachment 27008 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27008 adjusted test case This test case (adjusted to __builtin_abort() on error) fails with gcc-4.7-20120324 with -Os/-O2/-O3 on x86_64-pc-linux-gnu, but works with -O0/-O1, and works with gcc-4.6.3 and any -O option.
