[Bug c++/37556] New: [4.4 regression] ICE with invalid typedef

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

========================
struct A
{
  void foo();
};

typedef void (A::T)();

void bar(T);

void baz()
{
  bar(&A::foo);
}
========================

bug.cc:6: error: typedef name may not be a nested-name-specifier
bug.cc:8: error: parameter '<anonymous>' invalidly declared method type
bug.cc: In function 'void baz()':
bug.cc:12: internal compiler error: canonical types differ for identical types
void (A::*)() and void (A::*)()
Please submit a full bug report, [etc.]

The regression appeared between 2008-07-29 and 2008-08-23.

The bug is related to PR37555, but a more recent regression.
