On short final to Runway 18; we received a GPWS 'Too Low Terrain' Alert. The pilot flying initiated a go-around. Aircraft was on glide slope and airspeed. The visual was backed up by the RNAV glide slope. The PAPI was showing two red over two white.[This] could be an anomaly with the GPWS. There was a NOTAM on the RNAV for Runway 36 approach; noting terrain warnings and that the approach was no longer authorized.
The flight crew of a B737 received a GPWS Terrain warning for no apparent reason on short final to Runway 18 at BHM. They appropriately executed a go around.
