On AMD Athlon64 4800+ using gcc-Version 4.3.0 20070716
(x86_64-unknown-linux-gnu) with aermod of the Polyhedron benchmark suite:
http://www.polyhedron.co.uk/pb05/polyhedron_benchmark_suite.html
gfortran -fprofile-generate -march=opteron -ffast-math -funroll-loops
-ftree-loop-linear -ftree-vectorize -O3 ...
./a.out
gfortran -fprofile-use -march=opteron -ffast-math -funroll-loops
-ftree-loop-linear -ftree-vectorize -O3 ....
./a.out
This was still working on 12 July 2007; thus there must be a regression between
2007-07-12-r126572 and 2007-07-16-r126682.
The problem occurs with:
ac: Segmentation fault (core dumped)
aermod: Endless loop
doduc: Endless loop

Probably a dup of PR32773.

Mark as duplicate. At least ac does works after reverting the patch.
