Seems to be a compiler issue. do_bitwisenot() works fine.

ffc script NOTTest
{
    void run()
    {
        int x=1;
        int y=~x;
    }
}

This shouldn't be quarantined...

Which variable are you having trouble with here, Mr. Saffith?
And sorry if I moved this to the wrong forum by mistake...

Well, I was wrong. do_bitwisenot() was the problem, after all. 😛
Anyway, it's fixed now.

Those groups of three numbers in the output there? Each set should have been three of the same number.
