Testcase description:

(1)make a swf file bigger than 64KB. (eg. a 200KB file with 100 frames)

(2)add following actions to the first frame:

trace(_root._framesloaded);  
trace(_root._currentframe);  // output:  1
_root.gotoAndPlay(1000);     // try jump to an un-parsed frame.
trace(_root._currentframe);  // expected output: _framesloaded + 1;
                             // swfdec's output is always 1

I haven't attached the test file, it's too big. You can make one easily. The test file itself doesn't have much special requirements. Just follow step1 step2 above should be ok.

It's up to you to decide if it is a big bug.
