Compiling the following invalid ocde snippet I get an ICE:
==============================
template<int> enum E { e };
==============================
bug.cc:1: error: template declaration of 'enum E'
bug.cc:1: internal compiler error: tree check: expected class 'declaration',
have 'exceptional' (error_mark) in pushdecl, at cp/name-lookup.c:641
Please submit a full bug report, [etc.]
The regression appeared with Kriang's patch
http://gcc.gnu.org/ml/gcc-cvs/2003-10/msg00781.html
Looks like some function cannot deal with the returned error_mark_node
in push_template_decl_real.
