Android NDK crashes to work on features that weren’t even called

I am trying to create an Android application based on Miracl crypto lib (C / C ++). I have added sources and sources to the jni folder. And he wrote a simple call to a function that loads shared_library and returns a string (with calls to C ++ functions, just returns a string). But the application crashes when starting A / Libc? Fatal signal 11 (SIGSEGV), code 1, error addr 0x0 in tid 17711

runs on Windows 7 / x64 Android Studio 1.1.0 Android r10d NDK

I build with the command ndk-build.cmd NDK_DEBUG = 1 NDK_LOG = 1
