Calculation results of undef-undef*i itself won't stall the calculator, but,
if you try to PRINT the result containing undef-undef * i,
the calculator will stall and reboot.
In these case, using cat befor PRINT will be a workaround for the problem.

IMHO, even if there's a workaround, no sequence of commands should ever be allowed to crash or even reset the calculator. If one is found, it should be fixed ASAP with an out-of-band OS release or patch. That's the way the old HP would have done it (see the original HP-35 bug)
