zero ptr deleted in smart-pointer template. (g++-2.8.1)

[Yotam Medini]

Hello g++ developers:

Small but non trivial example. It involves manual instantiation
of smart-pointer template. 
By uudecode-ing and running make with the appropriate GCCROOT=
you should get more or less the following:

------------------------------------------------------------------------
rm -rf tst
mkdir tst
(cd tst; uudecode ../enc; gzip -cd sp.tar.gz | tar xf -; ls -l)

Hello

------------------------------------------------------------------------

A pointer member of template class is zero.
But for some mysterious reason, a 'delete' on it results 
in actual call to a member function with a bad this-pointer.

Putting all the template source together and eliminating
the manual instantiation removes the problem.
