[Boost-users] scoped_ptr, shared_ptr and pimpl

I have an object that uses scoped_ptr to point to it's impl...an 
incomplete type forward declared in the header and implemented in the 
cpp file.

This object *does have a user defined destructor*!  This user defined 
destructor is defined after the opaque type has been fully defined in 
the same cpp file.

In another cpp file I have a function that lives in the same namespace 
as the object in question, which creates a shared_ptr to this object.

I'm getting the "undefined type" error in checked_delete for the impl 
object.  I've run into this problem before but it was because I did not 
have a user defined destructor for the outer object...now I do.  I even 
created a blank destructor for the impl, something I've never had to do 
before.

What gives?  Any ideas where to look for the problem?  My simplest 
program that exhibits the problem doesn't exhibit the problem...I find 
this frustrating.
