Top Forums Programming Why this const variable is not changing even after applying const_cast? Post 302519144 by Corona688 on Tuesday 3rd of May 2011 06:12:41 AM

It's not unheard of for a compiler to do this even for non-constant variables, if it's convinced that nothing in the code ever touches the var. Things like:

Code:
static int debug_if=0; // Poke this value with your debugger when you want debug into to appear

...

if(debug_if) // ...but at high optimization, it might skip this anyway!
{
        fprintf("debug dump follows: ...\n");
        ...
}
