I still dislike the odd way in which the assertion needs to be formulated,
with the double negation. With the `ossl_is_null()` macro, which I proposed
in #7218, the same condition would read
if (ossl_is_null(ptr)) {
ERR_raise(ERR_LIB_WHATEVER, ERR_R_PASSED_NULL_PARAMETER);
return 0;
}
Isn't that much better readable and easier to understand?

Moreover, in the debug build you get the error message "Invalid NULL pointer:" instead
of a generic "Assertion Failed:"
