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

Bootstrapping the current tree-ssa branch on Tru64 UNIX (both V4.0F and
V5.1B) fails:

/vol/gnu/src/gcc/gcc-tree-ssa-dist/gcc/config/alpha/crtfastmath.c:46: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

This happens even when running

$ cc1 crtfastmath.i
