[Bug c++/28741] New: [4.2 regression] ICE with static member in invalid template class

[reichelt at gcc dot gnu dot org]

The following invalid testcase triggers an ICE on mainline:

=========================================
template<void> struct A
{
  static int i;
};

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

bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc: In instantiation of 'A<<expression error> >':
bug.cc:6:   instantiated from here
bug.cc:3: internal compiler error: tree check: expected tree that contains
'decl minimal' structure, have 'error_mark'  in decl_anon_ns_mem_p, at
cp/tree.c:1408
Please submit a full bug report, [etc.]

This is probably fallout from PR 27668.

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-08-18 04:46 -------
Actually I don't think this is fallout of that patch but really of the
anonymous namespace changes which added decl_anon_ns_mem_p.

Confirmed.

Most likely introduced by:
2006-06-29  Jason Merrill  <jason@redhat.com>

        PR c++/21581
        PR c++/25915
        * tree.c (decl_anon_ns_mem_p): New function.
