This GCC version does not make sense: 4.4.0-20060501. I assume you mean
20080501.
The mentioned file is available at:
http://www.netlib.org/lapack/single/sgtrfs.f
I can reproduce the crash with:
$ gfortran -S -O2 -ftree-loop-distribution "sgtrfs.f"
sgtrfs.f: In function sgtrfs:
sgtrfs.f:1: internal compiler error: Segmentation fault
Valgrind shows:
