Crash in native

Hello friends!
Furthermore, our customers use our application with the library. But the errors that lead to the collapse of the native application!
We have been searching for the cause and found it!
When you add annotations Congress with values 0.0 points several times crash occurs. I wrote about this :

The most interesting is that when I use the initialization of the library and demo project, everything works without errors ,
but when I use my key, there is a crash the app!

This issue is available on all versions available for download.
Please correct this problem, our customers are very angry with us.

May you provide some reference about your purchase?
Open a support ticket and write your order reference number or the email address you've used to finalize the purchase process.
Searching with your name and website email address I'm not able to find any purchase.

What do you mean with "annotations Congress"?

I'm sorry it was a mistake, "annotations Congress" iit should be annotations INK.
And my e-mail "kochergov( d o g )mrsoft.by"

And I repeat code that causes a crash:

A double check, are you activating a Professional or a Premium license.
The activation with the demo key is for a Premium license (type=2).

In the meanwhile I confirm that annotating API are available on both Premium and Professional.

Yes we have a professional license, and we are constantly adding annotations in PDF documents. And everything works fine, but sometimes there are documents that have to annotate with the coordinates x = 0, y = 0 and there is an application failure.
But if you use a key with a demo application, then this is no error.
Error leads to a drop in applications with the log:

10-16 10:52:59.146 309-353/by.mrsoft.mrdoc A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 353 (Service to SOAP)

Hi,
can you please give us the complete code to reproduce it? And where you place this lines?

Thanks!
