[Bug c++/39055] New: [4.2/4.3/4.4 regression] ICE with questionable default parameter of a member function

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following valid code snippet triggers an ICE since GCC 3.4.0:

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

A<0> a;
==============================

bug.cc: In function 'void foo(int) [with int <anonymous> = 0]':
bug.cc:4:   instantiated from 'A<<anonymous> >::A() [with int <anonymous> = 0]'
bug.cc:7:   instantiated from here
bug.cc:4: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

GCC 3.3.x wrongly rejected the code ('i' as default parameter is not OK,
but this should only be diagnosed if the default parameter is actually used).

GCC 3.[012].x correctly accepted the code.

Btw, the code compiles fine if A is not a template class.
