Bus Errors: Corona Bug or Error in Code

I am currently getting this error and corona crashes:
/Users/myMac/Desktop/CoronaSDK/Corona Terminal: line 9: 27835 Bus error: 10 "$path/Corona Simulator.app/Contents/MacOS/Corona Simulator" $*

Is this a bug with Corona or is there an error in my code?

Here's a great post relating to bus error, why it happens and how you might be able to go about fixing it:

Good luck!

Not a Corona bug, but likely an error in your code - are you using physics?

Does it happen under certain situations? Like on removal of physical bodies ?

The first time it happened was after leaving a scene that had physics with director, so it would have made sense. I would have assumed it had something to do with the physics. But after that it started occurring when on scene that does not have physics(and no physics up to that point). The scene that it crashes on only has transitions and timers. It doesn't happen every time but it is very worrisome.

Are you canceling your active transitons/timers before changing scenes?

Yeah, I actually created a director wrapper that candles all transitions and timers. I can post the code and the mac crash report. Just let me know what is the best way to post it.

Thanks

Okay this is getting really frustrating. I am putting the app on my phone, and it crashes or restarts the app on that same screen.

This is ridiculous. Why doesn't this code work???? It crashes during playFirst on my phone and crashes Corona randomly on all scenes. The other ones rarely work when they want to. What is going on? And I am not getting any errors from Corona or Director.

Someone ever solved a bus error ?
" exited abnormally with signal 10: Bus error active (but IDLE) sessions

No sorry. I ended up rewriting the whole thing and redoing all my images.
