--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Checked build of trunk segfaults here:

0x0000000000813619 in prep_operand (operand=<eq_expr 0x7ffff19edf28>) at
../../src/gcc/cp/call.c:5404
5404          if (CLASS_TYPE_P (TREE_TYPE (operand))

where TREE_TYPE (operand) is NULL.

Release builds of 7, 6 (and 5) handle it via the "confused by earlier errors,
bailing out" ICE.
