Something very strange just happened. Ollie and I tried using a SST49LF080A and it worked perfectly. The specifications on this part and the 49LF040 are exactly the same except for the device ID.
Perhaps there's a bug in the 49LF040? We do not have any 49LF040A parts in our lab at the moment that we can test with.
