[Bug target/32457] New: [4.3 Regression] Complete program optimized away (i686, -ftree-vectorize)

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This is with the polyhedron test gas_dyn.f90
http://www.polyhedron.co.uk/pb05/polyhedron_benchmark_suite.html

It only occurs for gas_dyn.f90 and only with -m32 (-m64 is ok).
This is with gcc-Version 4.3.0 20070621 on x86_64-unknown-linux-gnu.

gfortran -m32 -march=opteron -ftree-vectorize -O1 gas_dyn.f90

time ./a.out
