crash test case

Hello,
I'm currently developing a new fuzzing feature, and I found a crash in nm.

It crashed in __memcpy_avx_unaligned () at
../sysdeps/x86_64/multiarch/memcpy-avx-unaligned.S:245

I built it with Ubuntu 16.04 with gcc 5.4.0, and the following command to build
nm from the source:
./configure --enable-targets=all ; make clean all -j 4; make install

You can reproduce the crash with the following command:
./nm <attached file>

The call stack of the crash is:
Program received signal SIGSEGV, Segmentation fault.
