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 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.
