Gating the code doesn't actually hide the perf problem. Because the perf
problem occurs in getPresumedLoc which calculates line and column number.
The debug code was calling getPresumedLoc twice once to only get the line
and once to only get the column, but this results in line and column
actually being calculated twice.
Perhaps the debug code should be refactored to only call getPresumedLoc
