I'll add four cents to the kitty.

One of the people I work with had frequent but unpredictable crashes with
iTools on his Dell laptop. (Utter crashes right out of IDL, as with
invalid memory access.) We couldn't repeat these crashes on other PCs
around here. Coyote-like bug, aside from the lack of subtlety. Turns out
he needed a video driver update. That fixed it.

I have noticed a rare floating-point bug with CISCO VPN Client version 4.x.
With this client running and connected, I get the occasional floating-point
corruption in my program. (A regular app, not some kind of network thing.)
I'm pretty sure it's caused by VPN client although I don't know exactly how.
My program is all in C - no IDL - but I would expect the same thing applies
to any code that gets stuck into a serious amount of FP calculations. The
problem seems fixed in CISCO VPN client version 5.
