assert() function not showing up in disassembly
===

My coworker just asked me to help on a problem, he has a few lines in his code as

    for (long counter = 0; counter < End; )
    {
      ...
      assert(counter++ < MAX);
      ...
    }
    

The problem is, when we use Visual Studio to debug line by line, seems the assert() line got skipped all the time, and `counter` never got incremented and thus the loop never finished. 

When we look at the disassembly using VS, there is no assembly line for this assert() function. I never used assert() before, so I'm wondering is this normal and he shouldn't put any code behavior into assert() or something is wrong here with debugger or other?

Thanks.
