Yesterday I moved my project from OpenCV 2.4 to 3.0. I've tested the code in VisualStudio. Everything works fine, but in Android I'm getting errors when I'm trying to run the code. I've built the library with OpenCL enabled (see code bellow). A simple example app, that does edge detection on CPU/GPU works fine, but the app, which was 2.4.x previously is getting weired errors:
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x9
I'm accessing a Mat comming from Java-Side by its Jlong-Adress:
Mat& I_h_temp = *(Mat*)in_addrRawHolo;
Then I do some conversion:
I_h.convertTo(I_h, CV_64FC1);
sqrt(I_h, I_h);
There is an error comming and the App crashes:

The exact same code works with the old Version. I think there is a problem with the library? I've built it using
set PATH=%PATH%;C:\Users\Bene\Downloads\ninja.exe
mkdir OpenCVCL3
cd OpenCVCL3
cmake -GNinja -DCMAKE_MAKE_PROGRAM="C:/Users/Bene/Downloads/ninja.exe" -DCMAKE_TOOLCHAIN_FILE=C:/opencv3cl/platforms/android/android.toolchain.cmake -DANDROID_ABI="armeabi-v7a with NEON" -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DWITH_OPENCL=YES C:/opencv3cl

Any ideas?
