Hello,
I have looked into the problem, it seems to be caused by the return type
of cipher_kt_mode() in crypto_backend.h being declared as a bool. This
function is called from init_key_type() of crypto.c during the tests. The
actual mode value in cipher_kt_mode() of openssl_backend.c during the
failed test is 2, but is converted to 1 due to this boolean return type.
My guess is that this is only happening on OS X because of a specific GCC
compiler version or custom Apple patches.
Below I have included a patch that changes the bool return type to an int.
This will result in 'make check' to pass.
