Oh that...
Well, my program did something like 100000000/(28*cclk), but CGfx3 sets
current_tot_cclks to zero, so the expression above on most machines causes a
division-by-zero error.
When the Doom ports first came out, there were areas in the game where
firing (or even looking) straight down an axis could cause a
division-by-zero, so someone wrote a patch to trap the div-by-zero exception
and return machine infinity instead of causing a crash.
I suspect you've still got something like this installed, because the wacky
value returned was about 4 billion - or precisely 2^32-1 - machine infinity!
Could just be CyberPatcher/OxyPatcher or something similar - I don't know
exactly which programs patch what...
All the best,
