Q:

Actionscript VerifyError: The ABC data is corrupt, attempt to read out of bounds

Getting a VerifyError using the TweenMax lib when calling TweenMax.to.  This error doesn't seem to be specific to TweenMax (we've found other people having errors with unrelated code).  Perhaps someone has some insight into what this error means and what could be causing it. 
Edit
Seems like it's something to do with Anonymous functions: https://bugs.adobe.com/jira/browse/SDK-14054
Here's the error:
VerifyError: Error #1107: The ABC data is corrupt, attempt to read out of bounds.  at global$init()

And the full error:

A:

You found a bug in the compiler.  The best what you can do now is try figuring out what caused the bug and file a bugreport at bugs.adobe.com
As a side note.  It is very rare to find nowadays bugs in the Java compiler for instance.  The ActionScript compiler has still a lot of issues with strange control flow etc.
