The file below gives "internal compiler error: in cp_parser_template_id, at cp/parser.c:8564".  It's a 
Delta-reduced version of a preprocessed version of the Boost file remote_call_manager.cpp, but 
missing some header files.

class remote_call_manager: private noncopyable
{
    template<class R>
    static R execute_now(function<R> &rFunctor);
           inline void remote_call_manager::execute_now<void>(function<void> &rFunctor)

    This sounds like bug 9781, among others, but that's supposedly fixed.
    Here's the session:

g++ (GCC) 4.0.2 20050728 does not ICE for me on the reduced testcase, but instead
mainline does with a slightly different ICE:

pr23307.ii:5: internal compiler error: in cp_parser_template_id, at cp/parser.c:8660

#0  fancy_abort (file=0xc417b2 "../../gcc/gcc/cp/parser.c", line=8660,
    function=0xc43a64 "cp_parser_template_id") at diagnostic.c:590
#1  0x00000000004f4c03 in cp_parser_template_id (parser=0x2a958963c0,
    template_keyword_p=0 '\0', check_dependency_p=1 '\001',
    is_declaration=0 '\0') at parser.c:8658
#2  0x00000000004f9609 in cp_parser_class_name (parser=0x2a958963c0,
    typename_keyword_p=0 '\0', template_keyword_p=0 '\0', tag_type=none_type,
    check_dependency_p=1 '\001', class_head_p=0 '\0', is_declaration=0 '\0')
    at parser.c:12521

I question the use of asserts in paths of the compiler where we might deal
with errorneus input.  Why not return error_mark_node instead?  Which fixes
the ICE btw. -- I'll prepare a patch.

Richard.

4.0.0 ICEs for me so does 3.4.0. 3.3.3 does not.

Nathan didn't like my fix.  Some C++ frontend guy needs to look at it then
(unassigned myself).
