Re: CW and uninitialized variables

I came across a bug in my code where my variable wasn't being initialized.
It went something like this:

    Boolean isZero;
    UInt16 a = 3;
    if (a == 0)
        isZero = true;
    myFunction(isZero);

I'm not getting warned that "isZero" never gets set.  I looked around for a
setting but didn't find anything.  Is there a way to make CW detect bugs
like this?

Try turning on your optimizer, level 1 or higher. With that, it would have detected the dead code for isZero = true, and would then notice that izZero could not have been given a value at its use in myFunction. Without the optimizer on, it doesn't track values, so it doesn't know the set will never happen.
