[GoogleCodeExporter]

IOS application uses 2D barcode reader, native static library by
https://github.com/PDF417/pdf417-ios.
After 2-3 barcode reader calls application freeze.
Build with new VM.

What steps will reproduce the problem?

Previous few days build with new VM freeze.
Build with old VM working good - barcode reader can be called many times.

IOS 7.1, 8.1.3

It's very hard to make simple test case.
Every simple project works good.

On the project that we have problems with 
situation has changed since sunday 22. feb.

After build same application does not freeze any more but crashes
after staring barcode scanner SECOND time.
It crashes after barcode recognition on callback in IOS native code.

This is the line where application crashes:

hr_kaba_bcscanner_BCScanner_scanCallback__(CN1_THREAD_GET_STATE_PASS_SINGLE_ARG)
; 

Here is console output:
