>Environment:
GNU C++ version 3.2 (sparc-sun-solaris2.9)
        compiled by GNU C version 3.2.
>Description:
One template function is given directly. An overload version of this function is created via "restricted templates, i.e. given
(1)	dummy(const V<T> &, const V<T> &)
and
(2)	dummy(const U &, const W&).
Now (2) gets instantiated in a way that the two signatures
become somewhat identical. In that case gcc stops with "Internal error", "segmentation fault".

 
>How-To-Repeat:
just compile.
