have a similiar build failure, but seen with both 4.6 and 4.7, so this seems to
be a 4.6 regression too. works with -O2 and below.
fails with 4.6 20110428 and trunk 20110419.
$ gcc -g -O3 -c psf.i
psf.c: In function 'psf_fit':
psf.c:300:6: internal compiler error: Segmentation fault
Please submit a full bug report,
Program received signal SIGSEGV, Segmentation fault.
