The patch I refer to is one I made that didn't make it into the most recent version of yapppack.
YP uses an array as internal storage, and walks through it with a for i in 1..n loop. Since arrays are sparsely populated there is a fair chance of hitting an array element that does not exist. The patch consists of rewriting the loop with array.first/next/last in a while loop to avoid the problem. Yes, it is high level, but it can pinpoint time periods that you may want to investigate.
