shmget returns an ID, not an address. I quote from the Single Unix
Spec:
Upon successful completion, shmget() returns a non-negative integer,
^^^^^^^^^^^^
namely a shared memory identifier; otherwise, it returns -1 and errno
will be set to indicate the error.
While your change might be harmless, it should not be necessary, and it
certainly shouldn't have anything to do with 2gig address boundaries.
