I have fixed this particular case by checking the literal value of the filter expression at compile time (before bytecode generation). This won't fix the case where a large subscript value is computed dynamically, however, this is sufficient of an edge case that I don't feel compelled to investigate it until some user reports that they are affected by the problem.
