These are interesting.
I mean of course I did insert new variables, and assigned some functions as well. But I use static arrays, and this makes such overflows (as far as I know) impossible, as if I try to write to them I'd run into exceptions upon programming, not only upon execution (since nothing changes, but in one case I compile&run&debug, and in the other I just run the exe).
Is there anything in C builder which would make these kind of errors traceable during development? Is there a way I can monitor the memory usage of my program? I didn't really need to use advanced C builder features until now...
