An ICE occurs in stage1:

../../gcc/gcc/libgcc2.c: In function `__divdi3':
../../gcc/gcc/libgcc2.c:757: internal compiler error: Segmentation fault
Looking at this under gdb:

The cause appears to be one of these two patches:
<http://gcc.gnu.org/ml/gcc-patches/2003-02/msg01754.html>, or possibly
<http://gcc.gnu.org/ml/gcc-patches/2003-02/msg01755.html>.
