Ok I was able to reproduce this with the intel compiler turning inter_procedureal optimalisations on.

As far as I can see from the stacktrace, it happens when during loading of the VM an exception is thrown in the VM. This fails the call to the CreateVM(). If I turn the optimalisations off, it works fine as far as I can see (the dl_dlsym()code is not inlined then). 

This patch can be ignored, I'll file a bug-report with Intel.
