["hans dot buchmann at fhnw dot ch" <gcc-bugzilla at gcc dot gnu dot org>]

Preprocessing an empty file with a wrong -mfpu value results in:

empty.c:1:0: error: invalid floating point option: -mfpu=xxx
empty.c:1:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

 -mfpu=xxx  empty.c
