User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.56 Safari/536.5 Steps to reproduce: The VM currently handles SWFs differently than the player w.r.t. abc parsing/execution and the handling of the lazy flag in the swf. In our case we have several ABCs with the the lazy eval flag in the swf tags set to false. In the player all the ABCs are visited in file order and their traits read (prepareActionBlock). Whilst visiting the ABCs any non-lazy ABCs are added to a queue in file order (see QueueAbcBuffer in PlayerAvmCore.cpp:1887). Once a ShowFrame tag is encountered the last script init for each ABC in this queue is executed. This allows non-lazy ABCs to contain forward references to traits in ABCs later in the SWF. The shell currently walks the ABCs in file order and either reads the traits (via parseActionBlock) if the ABC is marked as lazy, or reads the traits and executes the last script init if the ABC is non-lazy. This results in ABCS with forward references to traits failing with reference errors.
