[Bug c++/16716] New: [3.5 regression] ICE in cp_parser_parse_and_diagnose_invalid_type_name

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Take this (invalid, the "typename" shouldn't be there) piece of code: 
------------------- 
template <typename> class allocator; 
 
template<typename T> class vector { 
    typedef typename allocator<T> allocator_type; 
}; 
------------------ 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc 
x.cc:4: syntax error before `;' token 
 
g/x> /home/bangerth/bin/gcc-3.3*/bin/c++ -c x.cc 
x.cc:4: error: parse error before `;' token 
 
g/x> /home/bangerth/bin/gcc-3.4*/bin/c++ -c x.cc 
x.cc:4: error: expected nested-name-specifier 
x.cc:4: error: `allocator<T>' specified as declarator-id 
x.cc:4: error: two or more data types in declaration of `allocator<T>' 
x.cc:4: error: expected `;' before "allocator_type" 
 
g/x> /home/bangerth/bin/gcc-3.5*/bin/c++ -c x.cc 
x.cc:4: error: expected nested-name-specifier 
x.cc:4: internal compiler error: in 
cp_parser_parse_and_diagnose_invalid_type_name, at cp/parser.c:2268 
Please submit a full bug report,

That's a regression.
