Test case #1

The attached program binary causes a buffer overflow in cplus-dem.c when it
tries to demangle specially crafted function arguments in the binary. Both the
buffer size as well as the buffer content are controlled from the binary.

Tested on the following configurations
* 2.6.32-573.7.1.el6.x86_64 #1 SMP Tue Sep 22 22:00:00 UTC 2015 x86_64 x86_64
x86_64 GNU/Linux
* 4.1.12-boot2docker #1 SMP Tue Nov 3 06:03:36 UTC 2015 x86_64 x86_64 x86_64
GNU/Linux
* Binutils versions: 2.20 and 2.26

Best regards,
- Marcel
