Off-by-one error in FastString.getFastStringTable
There is an off-by-one-error in FastString.getFastStringTable
that causes GHC to segfault when passed the -dfaststring-stats
flag due to accessing contents past the end of an array.
The fix is simple: replace hASH_TBL_SIZE
with hASH_TBL_SIZE-1
in the offending function.
