The following Fortran testcase exhibits a failure with -O(>=1) -msse:
$ cat foo.f90
subroutine yhalf(z)
complex cdexpj,z
z=cdexpj((0.d0,1.d0)*z)
end
$ gfortran -c -O3 -msse -mfpmath=sse,387 foo.f90
foo.f90: In function ‘yhalf’:
foo.f90:3: error: unrecognizable insn:
(insn 13 12 14 3 (set (reg:DF 63)
(neg:DF (reg:DF 62))) -1 (nil)
(nil))
foo.f90:3: internal compiler error: in extract_insn, at recog.c:2077
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
$ gfortran -c -O3 -msse2 -mfpmath=sse,387 foo.f90

I think it was caused by:
http://gcc.gnu.org/ml/gcc-patches/2006-05/msg01526.html
Which means this is a 4.2 Regression.
