In the interpreter, I've found two places from where this error is raised
(there might be more):

  1. When a Float or Long is converted to a Single but the Float/Long
     is too big: Print CSingle(2 ^ 500)

  2. When Date arithmetic produces a value outside of 32 bits:
     Print DateDiff(CFloat(2 ^ 50), CFloat(1), gb.Second)

The JIT compiler header adds another source of overflow checks.
Without the source code -- who can know?

Regards,
Tobi
