Using test_fpu.f90 of the Polyhedron testsuite,
http://www.polyhedron.co.uk/pb05/polyhedron_benchmark_suite.html, fails since
2007-05-15 (r124736) on x86_64-unknown-linux-gnu, 2007-05-14 (r124708) was
still ok. Last tested: 2007-05-20 (r124860).
The ICE occures with:
gfortran -O3 -ftree-vectorize -ffast-math -funroll-loops test_fpu.f90
With -m32 the ICE does not occure.
Running GCC through valgrind shows:
