Invalid memory access of location error when exporting for iOS

Question

I have been recently been asked to convert a flash application for us on the iPad. When I try to publish the .ipa file I end up with the following error:
Invalid memory access of location 0xceip=0x55492db4
I have no idea what might cause this and my google search of the error message has come up pretty empty. If I remove the document class and republish it works fine so I know it has something to do with my code but I haven't the slightest idea where to start looking so I was hoping someone else had run into a similar error and could point me in the right direction.
thanks so much

I managed to figure this out through laborious guess and check. Just thought I would share the bug in case anyone else ever runs into it.
A third party library I was using wrote try catch statements wrong:
try{
catch(Error:*){
No idea why the original author did it like this, probably meant to write "error:*" and didn't release shift fast enough after the "(" but as you might suspect "Error" is a reserved object name to cannot be declared as a paramenter variable
when replaced with:
try{
catch(error:Error){
the memory access bug went away. What is strange is that the incorrect try/catch statement works just fine when published to swf, air, or android and is only an issue with the iOS converter, and obviously produces a very cryptic error.
I was using CS5.5 so maybe this has been fixed (if not I would suggest making this a compile time error) but just thought I would post my findings.
