#define LIKELY(x) (x)
#define ZZ
class A
{
    void a()
    {
        int x = 0;
        if LIKELY(x) ZZ // remove "ZZ" to watch changing of "VAOutline"
        {

        }
    }
    void b()
    {

    }
};

wihtout "ZZ", VA parse the code wrong.

Thank you for the clear example, I have seen odd things like this before, occasionally. I think this is covered by:

case=149467

so I have added this example to the case. Thank you for finding and sharing the work around, that is interesting! I can see people not liking it, but it is good to have the option regardless.
