The dragonegg svn plugin, llvm svn and FSF gcc 4.6.3svn miscompiles the
Polyhedron 2005 aermod.f90 benchmark under x86_64-apple-darwin11 when the new

aermod binary fails with the run-time error...

This occurs with -msse4 at all optimization levels, -O0/-O1/-O2/-O3.
The problem doesn't occur without -fplugin-arg-dragonegg-llvm-option=-vectorize
 or when only -fplugin-arg-dragonegg-enable-gcc-optzns is used in its place.
