Gack.  My mistake.  0x47505344 clearly is GPSD, not NTP4.

8248 is sizeof(struct gps_data_t) 

So this is an occasional.  Things like building with qt=no will change
the size of gps_data_t.  Any shmid laying around from prior to a
change will be the wrong size.

The test code just needs to delete shmid 0x47505344 before and/or after
it runs the tests.
