Confirmed, this is a regression on the 3.3 branch against
3.2 that compiled this fine. Mainline is fine as well. Here's
what I get with 3.3 compiled with checking enabled:

g/x> /home/bangerth/bin/gcc-3.3*/bin/c++ -c x.cc
x.cc:6: internal compiler error: tree check: expected identifier_node, have
   template_id_expr in grokfndecl, at cp/decl.c:9594
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Kriang, you have done all that great work in this area lately --
is this something that you think is possible to fix on the
release branch?

W.

This the patch I fixed in the mainline

  http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01682.html

I'll check to see if 3.3 branch needs the same or different
fix.

Just a remark: It's already fixed in GCC 3.3.2
(and not only in 3.3.3 as Mark wrote in comment 8).
