Something is probably misconfigured on your system.

If cryptsetup binary itself works, try to add debug info to your program:

crypt_set_debug_level(CRYPT_DEBUG_ALL);

and also try to strace it (do not use valuable password though:)

If it there is still not useful explanation in log, please send the output =
of these logs.

Thanks,
