>Description:
First of all, I am not sure if the code is really leagal. But a least I get
an ICE for sure.

If you create a templcate class without specifying a (default) constructor but
you provide later a specialised (default) constructor. I get an ICE.

The same applies for 
	GNU C++ version 2.95.4 20011002 (Debian prerelease) (i386-linux)
	compiled by GNU C version 2.95.4 20011002 (Debian prerelease).

>How-To-Repeat:
# 1 "tempspec.cc"
template<class T>
struct Foo
{

};

Foo<int>::Foo()
{
}

void bar()
{
        Foo<int> f;
}
>Fix:
Pretty easy. Just add the "prototype" of the constructor in the
unspecialised template declaration.
