A simple trick gets you around this: Don't use your system malloc() but instead map a tempfile (or a memfd) with MAP_SHARED and use the STM primitives to update your references. If you combine this trick with __attribute__((address_space(256))) your "pointers" are also the offsets in the tempfile. Or don't: Maybe you want two heaps. fork() gives you the option!
