Actually it's catched by CATCH_THROW_AND_RETURN(env, 0) in ​https://github.com/adblockplus/libadblockplus-android/blob/master/libadblockplus-android/jni/JniFilterEngine.cpp#L338 or ​https://github.com/adblockplus/libadblockplus-android/blob/master/libadblockplus-android/jni/JniFilterEngine.cpp#L299.

This is how it works:

#define CATCH_THROW_AND_RETURN(jEnv, retVal) \
  catch (const std::exception& except) \
  { \
    JniThrowException(jEnv, except); \
    return retVal; \
  } \
  catch (...) \
  { \
    JniThrowException(jEnv); \
    return retVal; \
  }

So something is cached by catch(...):
signal 6 (SIGABRT), code -6 (SI_TKILL), fault addr --------

ACCESS_WIFI_STATE and ACCESS_NETWORK_STATE permissions are requested AndroidManifest.xml

seems like it's same issue
