Failed to debug using gdb for Android and NDK, launching the Gdb crashes application

I'm having trouble debugging my own code using the Android NDK.

While the application is running, I start ndk-gdb , and the result is that gdb loses connection with the device and the application on the device crashes.

The same thing happens with the device (Samsung Galaxy 10.1), and with the emulator. Mac OS X is installed on the host computer. The native part of the application consists of several .so libraries using ndk-build clean all NDK_DEBUG=1

I have connected the gdb output below.

Any help would be greatly appreciated.

Edit: Maybe the problem is due to a cp command error? And the empty line "Using gdb setup init:"?

I had the same problem. Turns out the problem was that I was running ndk-gdb in the $ PROJECT_DIR / jni folder. Level shifting and execution from $ PROJECT_DIR fixed shutdown.
