I think you've found a subtle bug in the PD source,
but I can't get spectrum.exw to crash no matter what I do.
I've interpreted it with exw.exe, and exw eu.ex.
I've translated eu.ex with Watcom and with Borland to get eu.exe.
I've translated spectrum.exw with Watcom and Borland.
It always runs fine. 
I'm having it play the APPEAL.MOD file in the same directory.

What data file did you run it with?
