[Bug c++/27806] New: [4.0/4.1/4.2 regression] ICE with invalid ptr-to-member

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since GCC 3.4.5:

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

void foo()
{
    p;
    extern int A::* p;
}
=====================

bug4.cc: In function 'void foo()':
bug4.cc:5: error: 'p' was not declared in this scope
bug4.cc:6: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in original_type, at cp/typeck.c:231
Please submit a full bug report, [etc.]
