I had
void operator=(const jArray<T,L>& other)
where jArray is a struct and
void operator=(L zero)
where L is in practice int32_t and argument zero is only ever 0.
The person who did the nullptr conversion was apparently not OK with
the nullptr to 0 implicit conversion causing a warning, so I figure I
must not re-introduce that conversion.

This seems to work. Thanks.
Now I have:
void operator=(const jArray<T,L>& other) {
delete[] arr;
arr = other.arr;
length = other.length;
}
#ifdef MOZ_HAVE_CXX11_NULLPTR
typedef decltype(nullptr) jArray_nullptr_t;
void operator=(jArray_nullptr_t zero) {
// Make assigning null to an array in Java delete the buffer in C++
delete[] arr;
arr = nullptr;
length = 0;
}
#else
void operator=(L zero) {
// Make assigning null to an array in Java delete the buffer in C++
NS_ASSERTION(!zero, "Non-zero integer assigned to jArray.");
delete[] arr;
arr = nullptr;
length = 0;
}
#endif
