Based on FreeBSD patch. The FreeBSD inclusion of check_openssl_compatibility prevented any use of the crypto callbacks and as such the later differences where ignored. The later differences in coc_malloc didn't propegate to the other callback functions of CRYPTO_set_mem_functions where a reduced argument list also applied. Looking where[2] libressl added the functions it was of the same prototype 10 years ago so omitting any version check.
