collector. Some code in the Go standard library (notably sync.copyChecker)
seems to assume that the following holds:
obj := new(something)
ptrA := uintptr(unsafe.Pointer(obj))
/* various stuff */
ptrB := uintptr(unsafe.Pointer(obj))
/* Does this hold? */
ptrA == ptrB
Does this assumption hold? I.e. can I assume that once I convert an
unsafe.Pointer to an uintptr, the object I point to doesn't move in memory
anymore? I asked a question <http://stackoverflow.com/q/22195919/417501>about this issue before, but the results where a little bit inconclusive.
