CrystaX NDK

Hi,
my Android gradle project builds fine and starts to run on my Android device, however I always get a SIGSEGV at a certain line.
This project is a multi-platform project and all the other platforms (OS X, iOS) work fine. It also worked with Google's NDK r10d.
I'm also using OpenCV 3.1 and compiled it successfully with your cmake toolchain with the newest daily build.
I'm building for armeabi-v7a.
Is this a bug in Crystax or am I doing something wrong here?

I get the following stack trace:
