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.

Well, even 4.1.x seems to ICE with checking enabled, the ICE in
check_array_designated_initializer started in between r119500 and r120000.
