[Bug c++/18140] New: C++ parser bug when using shr (>>) in templates

[markus at oberhumer dot com]

gcc incorrectly rejects the following template code - seems to be a bug in the
new (gcc 3.4) C++ parser.

> g++-4.0 -Wall -W x.cpp
x.cpp:6: error: spurious '>>', use '>' to terminate a template argument list
x.cpp:6: error: expected primary-expression before "S"
x.cpp:6: error: expected %<;%> before "S"


template <int N> struct IntHolder {
    static const int value = N;
};

template <int N, int S> struct ShrIntHolder {
    static const int value = IntHolder< N>>S >::value;
};

Looks like caused by the new parser
: Search converges between 2003-12-18-trunk (#431) and 2003-12-24-trunk (#432).
