The stack trace suggests that the problem occurs when you are processing a for loop. And the assember instruction where the trap is occuring is the rep move ... which supports that.

From that, I'd hazard a wild guess that you have a for loop that running off the end of the data it is copying, and from the stack trace, it looks like that for loop is located in a module--maybe at line 32 of the file?

Like I say, that's mostly guesswork, but if your script doesn't have too many dependancies it might be worth looking at line 32 of each of them and seeing if there is a for loop there, before dismissing this completely :)
