Is it the kind of system for which memset(somestruct, 0, sizeof(somestruct)) doesn't work if the struct has pointers (NULL isn't 0, so null checks will fail if one inits such struct like this)?

NULL does not have to be 0 in the sense that it is represented by all 0 bits, it need only compare equal to 0.

Not really, NULL is still 0, but the address "0" is valid and readable/writable.
