[Bug c++/28250] New: [4.2 regression] ICE with invalid catch

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE on mainline:

=================================
template<int> void foo()
{
  try {}
  catch (int(0)) {}
}
=================================

  bug.cc: In function 'void foo()':
  bug.cc:4: error: expected `)' before numeric constant
  bug.cc:4: internal compiler error: tree check: expected tree that contains
'decl common' structure, have 'error_mark'  in pushdecl_maybe_friend, at
cp/name-lookup.c:574
  Please submit a full bug report, [etc.]

Will post a patch soon.
