Stack Frames make problem with collision

I posted this a while ago, thinking it was a problem with init variables in realse mode, but it isnt, i found out that when i turn on the "stack frames" runtime switch, my program runs fine in release mode. But when i turn stack frames runtime check off, then my collison system ("Tokamak Physics Engine") screws up majorly. Now, i would post this on the tokamak board, but no one has this problem before and has no idea what it is. Can anyone tell me more about "Stack Frames"? and how they would effect my program like this? Ive looked around on google and msdn and All i know is that it's used to keep track off the call stack of functions. How would what change my problem at all?
