[Bug c/35433] New: [4.1/4.2/4.3/4.4 regression] ICE with typeof and ternary operator

[reichelt at gcc dot gnu dot org]

The following (IMHO valid) code snippet triggers an ICE since GCC 4.1.0:

================================
typedef int* X;
typedef int* Y;

X (*p)[][0];
Y (*q)[][0];

typeof(*(0 ? p : q)) x = { 0 };
================================

bug.c:7: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

The code compiled fine with GCC 2.95.3, crashed GCC 3.0.0, 3.0.1,
and was rejected by GCC 3.0.2 - 4.0.4.
