Description

There is a subtle race condition. If the fpTable64 is not yet initialized and two thread try to compute FP for two schemas (or the same schema) at the same time, one thread will start initializing the table while the other can start using the partially initialized table giving wrong result.

The forthcoming patch fixes that issue
