Hi,

While I debug an application in VS 6.0, I noticed a strange behavior :

Value of a local variable (an int) increases by one for every single step.
Even when the line in which the variable initialized to zero is stepped out,
the variable is still getting increased :

void func ()
{
int i, j;

i = 0;
j = 0;
// At this point j becomes 1 if I execute above line as single step
and it keeps increasing for every single stepped lines...
i = 1;
// Now j = 2 !!!
j = 2;
// H�mm j = 3
}

Is this a known bug? If no, then what is wrong?

Thanks in advance...

Are you perhaps debugging an optimised build? Things can appear very
strange then!

If that's truly the code, then the problem is that i and j were not really
assigned any memory. In that case, the debugger doesn't really know where
the values of i and j are stored, so it has to guess.

Visual Studio 98 is ten years old. Unlike wine and cheese, software does
not age well. You need to get something newer.
