Does your main program export dynamic symbols (--export-dynamic in GNU 
ld) ? see here:
    http://www.nondot.org/~sabre/Mirrored/libtool-2.1a/libtool_9.html

If for whatever reason the dynamically loaded code needs to resolve a 
symbol at runtime, and this has not been exported by your main program, 
I would expect the code to either be terminated with a runtime linker 
exception, or fail silently.
