Memory limit in Air 20?

After upgrading Air SDK from 19 to 20, Crossbridge compile works fine.

But some error occurs from function that using memory.

Is there something like memory limit policy exists form version 20?

Below is error log with the problem:

Error: Error #1000: The system is out of memory.
