  Here I am again :-) 

the above program give an ICE output when I try to compile 
with the -g flag on (and u guess it, I need this flag to debug 
a program which is segfaulting):

$ g++ -g bug.cc
bug.cc:42: Internal compiler error.
bug.cc:42: Please submit a full bug report to `egcs-bugs@cygnus.com'.

the implied compiler is

The problem was that dbxout_type_methods did not deal gracefully with
a TEMPLATE_DECL.  I've attached a patch.  Jeff, may I check this in?
