Pointers are certainly not guaranteed to be the same width as int by the standard. The standard doesn't get to say anything about the size of the built-in types, which may differ by hardware and compiler flags.
void * p = ordered_malloc(s); get()->push_back(numeric::interval<int>((int) p, int((char *)(p) + s)));
There are many platforms in which int is not the same number of bytes as a pointer. Most commonly such casts will cause code to fail to port to 64 bit platforms.
