gcry_control( GCRYCTL_SET_THREAD_CBS, &gcry_threads_boost ); returns  
0x2000003c. What it means?

Actually what is the return value of gcry_control when setting them? Are you 
sure that these functions are not called?

I see here that you do:

and have no error checking whatsoever. Check gnutls_global_init() on how the 
initialization of libgcrypt is done. Otherwise you don't even know if these 
functions have any effect.
