Show the relevant code that returns "5".  Most frequently "5" is
SSL_ERROR_SYSCALL, returned by SSL_get_error().  As you note, this
value is never set as the verification result by OpenSSL itself, so
unless you have verify callbacks that change the X509_STORE_CTX
error value, perhaps you're reporting the return value of the wrong
