>Description:
While loosing overview of a small template metaprogramming
project, I happened to write something like
--------------------------------
template <typename ST, T> struct X {};

int main () {};
--------------------------------
The second template parameter of X is incorrectly given.

This crashes the compiler:

tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -c y.cc
y.cc:1: error: parse error before `>' token
y.cc:3: error: cannot declare `::main' to be a template
y.cc:3: internal compiler error: Segmentation fault
