Thanks for the report. The reason it is erratic and not always
reproducible in the same spot is that it is the result of an array
bounds error, and so depends on the contents of memory beyond the
end of a string.
I've fixed the problem, and the fix will be in the next release. If
you're interested in the fix, I've attached a patch.
