PoC

I have found a memory leak in xmalloc of Binutils-2.34. This bug is triggered
as
$./readelf -a PoC
I compile the binutils-2.34 to the 64-bit LSB version with AddressSanitizer in
Ubuntu 16.04 and print the debug information.

=================================================================

(/usr/lib/x86_64-linux-gnu/libasan.so.4+0xdeb40)
    #1 0x5614951da40c in xmalloc xmalloc.c:147
