[Bug c/32477] New: ice for legal code with -O2 -ftree-vectorize

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile Suse Linux package hwinfo-13.35-18 with the
GNU C compiler version 4.3 snapshot 20070622

The compiler said

i10_vbios.c: In function 'int10_bios_ok':
i10_vbios.c:154: warning: cast to pointer from integer of different size
i10_vbios.c: In function 'InitInt10':
i10_vbios.c:80: internal compiler error: Segmentation fault

Here is some additional help from valgrind
