I thought of one way, which is to remove the template constructor,
recompile, and count the errors.  Then, add the two-argument constructor
and do it again.  If the second compilation has fewer errors, then
there's some spot that calls the new constructor.

I don't think you should actually do this though, I'm not planning to
either.
