Flash IDE, Haxe & OpenFL - Invalid Data Swf Error #2136

Question

We've recently run into a show stopping issue and can't seem to find any one else on the net who has the same problem (although there have been similar ones).
We're currently developing a game using Haxe and OpenFL. We use FlashDevelop to code the game and the official FlashIDE (CS6) to create UI/menus which is then hooked up via code in FlashDevelop. A few weeks ago the FlashIDE crashed while the FLA was being worked on. Nothing appeared to be wrong as the file opened normally, however, after building our game in FlashDevelop we received the following message "Invalid Data Swf Error #2136". Since then we've done a handful of things that will seem to fix it temporarily, but as of now, none of those solutions work. At this point we think its some sort of flash limit or an issue with OpenFL, Haxe, and FlashIDE (or some combination of).
I'd like to note that we've noticed some weird behavior - if we removed any clip the error disappears and if we add it back, the error returns.
Here's what we've tried:
recreating movie clips that were created after the crash
converting the FLA into a archive and repairing it with WinRAR
splitting the FLA into two files
copying the library into a new FLA file
Any ideas on how to fix this would be greatly appreciated!

If you found a specific clip that caused it to build or fail I'd say it's a possibility. However you mentioned in the OP that you took 'any' clip out and it works but put it back and it breaks. This really seems like a limit. Limits should be openly documented however.
Perhaps you should take a large bitmap and a complex vector and drop them in 2 different symbols. Then duplicate these symbols until you have more symbols than you currently have. Internally they will all point to the same graphics so it won't be a heavy file. Try exporting that with OpenFL and see if it's a library reference limit.
I'm sure you get what I'm getting at. If limits arent documented, you may need to stress test the libraries, languages and frameworks yourself using simple self made tests.
