Neither of these happens with the TAP plugins here. 

If dlopen returns NULL the reason can be as simple as the
.so file not being there - you have to search LADSPA_PATH.

The OP wrote that this happens with his reduced-to-minimum test.
Then if the full test crashes on the same, there must be some 
bug in that test code, maybe something from a previous iteration
not being cleaned up.
