Crash on any SWF when using "Cache as Bitmap" in stage

[n1k1taar]

Describe what you were doing

I wanted to try the “Cache as Bitmap” function in the “Stage” panel, but I get this error, in all the swf I've run (Different animations by Touhou, Earn to die 2012, Raze 1)

What does the crash message say?

I think the stage should never be 'cached as bitmap' and that is why you get a crash
