You are using pthread, but you have not initialized gcrypt to use the
pthread mutex stubs.  Please refer to the documentation on how to do that.

I am waging a guess that this is already your problem.  The stubs used
for the non-threaded case use the assertions to check for locking
issues, but they rely on the fact that there is never contention in a
single-threaded program (otherwise it would dead lock anyway :).

So, if there is contention, and you didn't initialize gcrypt properly,
you will trigger the assertion.

A programming error in gcrypt could also trigger this assertion, but
this would show as a dead lock in the threaded case (if properly
initialized).

Thanks,
