[Bug c++/27582] New: [4.0/4.1/4.2 regression] ICE with invalid template parameter

[reichelt at gcc dot gnu dot org]

The following invalid testcase triggers an ICE since GCC 3.4.0:

===============================================
struct A
{
    template<int> void foo();
};

template<int N, void (A::*)() = &A::foo<N> > struct B {};

B<int> b;
===============================================

bug.cc:8: error: type/value mismatch at argument 1 in template parameter list
for 'template<int N, void (A::* <anonymous>)()> struct B'
bug.cc:8: error:   expected a constant of type 'int', got 'int'
bug.cc:8: internal compiler error: tree check: expected tree_vec, have
error_mark in any_dependent_template_arguments_p, at cp/pt.c:12751
Please submit a full bug report, [etc.]

Patch on the way.
