libc abi.dylib: terminate called throwing an exception

I have a very basic xcode project which is throwing the following exception

0x2c24b 0x1dcf8 0x1efddf9 0x1f25f3f 0x1f2596f 0x1f48734 0x1f47f44 0x1f47e1b 0x197da 0x1b65c 0x264d 0x2575)

libc++abi.dylib: terminate called throwing an exception

Can anyone help as the reason give no clues that I can work with.

Thanks
