Confirmed.

Starting program: /abuild/rguenther/gcc41-g/gcc/cc1 -quiet -O2 /tmp/bug.c

Program received signal SIGSEGV, Segmentation fault.
0x0000000000830372 in compare_values (val1=0x0, val2=0x2afe6fd01db0)
    at /space//rguenther/src/svn/gcc-4_1-branch/gcc/tree-vrp.c:431
431       gcc_assert (POINTER_TYPE_P (TREE_TYPE (val1))

This is a regression from 4.1.1.
