The typedef you use is still a specialization of a template, so you 
have to write 
 
template <> intsample::keytype * intsample::keyptr = 0; 
 
With this, it works.

This is invalid.

You want the follwoing instead:
template<> intsample::keytype * intsample::keyptr = 0;

Thank you a lot!
I'm sorry to report a false bug.
Just used with older version and thought that found a regression.
