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 function. -- Viktor.
