Reduced testcase

I made a minimal testcase using a Fortran-modified delta <http://gcc.gnu.org/ml/gcc/2009-10/msg00618.html> and attached it.

This is the line that fails:

x86_64-pc-linux-gnu-gfortran -march=corei7-avx -mtune=generic -ftree-vectorize -O2 -pipe -w -c small.f

If I add -mno-avx, -fno-tree-vectorize, or -fno-strict-overflow, it works. It's apparently some interaction of those things.

I was going to file a new bug, but it looks exactly like this one but in sci-libs/clapack-3.2.1-r6. It is triggered with -O3, with -O2 it builds fine.

Can't reproduce any of those reports.
@Donnie can you try with gcc-4.6.3?
Comment 6 Ryan Hill (RETIRED) gentoo-dev 2013-04-23 06:15:02 UTC
Reopen if this is still a problem with 4.6.4.
