crash when friend function defines template specialization

[Ian Haggard]

I'm enclosing a transcript in which I produce an internal compiler error that
is caused by the instantiation of a friend function which is defined in the
body of a template class.  The friend function is a specialization of a
function template.

This crash occurs both in gcc-2.8.0 and in egcs-1.0.0, so I'm sending the bug
report to both lists.

This was definitely a fun one to find, as the line number in my original
sources that was causing the crash was so far away from the line where the
internal compiler error was being reported :^)
