So it's not a shared library issue? Anyway, I wonder what got changed in such an old and perhaps not-so-much-used-today module... I would be very surprised if that code have been touched in many years. More likely some corruption of the stack or some data structure. If the same code previously worked, then I'd still start by pointing at some shared library, but there might also be common data with other parts of RTPAD, which have been changed, while the RSTSRT piece was not.
