Diafine, Film Speed, and fogging

[XAos]

I know as a general rule, faster film speeds are more prone to heat fogging, but how does Diafine's speed increase and constant contrast developing play into this? If I'm shooting Tri-X at 1600, does it fog faster/more than if I were shooting it at 400? Will it fog more or less than color 800 speed film? I keep color 800 in my Stylus, and it stays in an an un-airconditioned building for long periods of time. I try to change it out once in a while, but how long, how hot, and how does diafine affect all this? It seems like constant contrast would tend to work against the tendency to fog, but I also know that the system will break down (say if you accidently shoot it at ISO 100 because you forgot the camera defaults to that if there isn't a DX label).

I am not exactly sure I follow all the above but Diafine, like all other developers I know, will not save film damaged by environmental factors.

Yes, but you shoot it at 1600 and develop in diafine, will it fog like ISO 1600 or like ISO 400?

Tri-X will fog like Tri-X. It doesn't matter which EI you assign to it.

shooting like 1600 means underexposing by 2 stops.
Tri-X will fog the same way if you expose it normally, or over-underexposed.
