[Bug c++/30847] New: [4.1/4.2/4.3 regression] ICE with invalid statement expression

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The follwoing code snippet triggers an ICE since GCC 4.0.0:

=====================================
void foo(int i)
{
  (i ? 1 : 2) = ({ int X; });
}
=====================================

bug.cc: In function 'void foo(int)':
bug.cc:3: internal compiler error: in build_target_expr_with_type, at
cp/tree.c:382
Please submit a full bug report, [etc.]

The problem is similar to PR 30158, but alas not fixed with Andrew's patch.
It's even worse because it's not an error-recovery bug.
