Yes, when trying to load a module built for non-multithreaded Perl into a 
multithreaded Perl interpreter.  Perl can (I eventually learned) be built 
multithreaded or not, and dynamic libraries built for one cannot be used 
with the other.  It's a matter of compiling using Perl headers with the 
appropriate configuration.  Nothing to do with SWIG, really.
