Or the script could be reading a file that is changing.

Or it could be using the output of toc in a computation.

Or it could be calling an improperly written .oct file that has
undefined behaviour.

Or it could be running into a race condition during an asynchronous
operation (e.g. network communication).

Or there could be a call to a function that does invoke a RNG and
wasn't expected to do so.

Or the operating system itself may have memory/stack corruption.

Frankly, I still prefer my software gnomes theory. ;-)

I could almost bet (not really just emphasizing :) that the problem is the one i mention or the first from your list (the real one not the magic land). Btw is operating system memory corruption included in <common>....? Having the code will indeed help, i just mention what i ve learned through educational experience (90% of the problems with "random" behaving scripts i ve seen (written by students) are related to forgoten variables definitions).
