Thread: The "no source code available here" notice prevents debugging

Any time I have math in a function call and I press F11 in Visual C++ 2008 Express, I get a notice stating that there is no source code at the current location and a choice to either choose "OK" or "show disassembly", for which the latter makes no sense at all to me as I have no clue what any of it means. However, if I press F10 instead to skip over the function call, debugging continues normally. The only way around this problem that I know of is to temporarily remove the math from the function call. Here's an example on what I'm referring to:

Code:

int DoSomeMath(int a, int b)
{
   int c = 5;
   return a+b*c-7;
}

int main()
{
   int x = 9;
   
   DoSomeMath(3, x); // press F11 here allows me to go into the function normally
   DoSomeMath(2*x, 6*(x-3)-4); // press F11 here and I get the "no source code" notice and debugging won't continue
   return 0;
}

What can I do to stop this from happening? Can't the math just get evaluated then step into the function so I can debug the function?

I suggest trying to turn off all compiler optimization; and, verify that debug options are correct.
I rarely use VS so can NOT give any more help.
