This function returns a negative error code on error. When it does so, the `value_str` pointer will remain uninitialized and cause a crash later on when it is freed by OPENSSL_free(). Even if it wouldn't crash there, it still fails to signal the error and an empty string may be propagated to the callers. The check also mirrors the other one in the same file.
