[Bug c++/27961] New: [4.1/4.2 regression] ICE on invalid template declaration

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

The following testcase causes an ICE on the 4.1 branch and mainline:

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

bug.cc:7: error: 'X' was not declared in this scope
bug.cc:7: error: variable or field 'foo' declared void
bug.cc:7: internal compiler error: tree check: expected var_decl, have
field_decl in cp_finish_decl, at cp/decl.c:4933
Please submit a full bug report, [etc.]

This is a very recent regression, since GCC 4.1.1 is not affected.

Mark, your patch for PR 27819 seems to have caused this:
