Speaking of "not relevant" and "misunderstands the fundamentals":

1) UTF8String returns a non-__strong pointer.
2) You fail to copy the data at that pointer.
3) You cry foul when that data disappears.

Exactly. So stop getting your knickers in a twist about whether or not
UTF8String actually returns memory from NSAllocateCollectable(), and
simply copy the result as required by the documentation for
UTF8String.
