For more information you can try to set LD_DEBUG to a non-null value
in the execution environment - the shared loader should give you a
hint what's going on; as an alternative, you can add a call to
dlerror() at the place in question and print the string returned.
(The code should probably do that anyway, but if it already does and
dlerror() returned a null pointer that would be a bug in the shared
loader.)
