            Bug ID: 60224
           Summary: [4.7/4.8/4.9 Regression] ICE using invalid initializer
                    for array
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet triggers an ICE since GCC 3.3 (with the
exception of GCC 4.1.2):

==========================================
struct A {};

void foo()
{
  bool b[] = (int (A::*)())0;
}
==========================================

bug.cc: In function 'void foo()':
bug.cc:5:28: internal compiler error: unexpected expression 'int
(A::*)()::__pfn' of kind field_decl
   bool b[] = (int (A::*)())0;

Please submit a full bug report, [etc.]

GCC 3.2.x and GCC 4.1.2 work fine, i.e. they produce a decent error message
without crashing.

--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, even 4.1.x seems to ICE with checking enabled, the ICE in
check_array_designated_initializer started in between r119500 and r120000.
