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.
