Description

compc included in FalconJX 0.7.0 seems to crash on the following class:

FalconJXCrash.as

package
{

public class FalconJXCrash
{
    
    public function FalconJXCrash()
    {
        var foo:uint = generateInitialSeed();
    }
    
    private function generateInitialSeed():uint
    {
        var seed:Number = new Date().time - Math.random() * int.MAX_VALUE;
        return seed;
    }
}

}

Separating the calculation of seed into two lines seems to solve the problem.

The exception returned by FalconJX is this:
