"some_type* p_some_type = new some_type [0]" legal?

is it valid to call new [] to allocate 0 elements? If so, is p_some_type
NULL afterwards?

Yes, No.

Allocating 0 elements returns non-NULL pointer. The pointer will be
different each time. It's not legal to dereference the pointer, but it
is legal to pass it to delete[].

Usually this is exactly what you want.
