[Bug c++/29021] New: [4.0/4.1/4.2 regression] ICE on invalid use of "*" in template

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers a segfault since GCC 3.4.0:

==================================================
struct A
{
  template<int> void foo()
  {
    A().template *foo<0>();
  }
};
==================================================

bug.cc: In member function 'void A::foo()':
bug.cc:5: error: expected unqualified-id before '*' token
bug.cc:5: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Without the template keyword the compiler ICEs without a suitable error
message:

==================================================
struct A
{
  template<int> void foo()
  {
    A().*foo<0>();
  }
};
==================================================

bug.cc: In member function 'void A::foo()':
bug.cc:5: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
