That cannot be the explanation for the problem when I copy the
executable from machine A to machine B, since I have 3.13p on machine A.

I agree, but at the moment getting 12 MB onto machine B is difficult.

The program does not use tasking. Interestingly, the earlier version,
which does run OK on machine B, uses tasking. In the interest of getting
the program to run on Linux I removed the tasking.

The sources are quite long and (for the moment) proprietary.
