Dear all,

The following bug was found with AFLFast, a fork of AFL, in a 24 hour fuzzing
session on Binutils. Thanks also to Van-Thuan Pham.

The linker reports an internal error for Binutils in trunk and crashes for
Binutils v2.26.1 and v2.24.

$ printf
"\x08\x01\x00\x00\x08\x00\x00\x00\x04\x00\x00\x00\x00000\x60\x00\x00\x00\x00000\x00\x00\x00\x00\x00\x00\x00\x00\x0000000000000\x02\x00\x00\x00\x18\x23000000\x06\x00\x00\x00\x140000000\x00\x00\x00\x00\x140000000\x02\x00\x00\x00\x180000000\x06\x00\x00\x00\x1e0\x0900000\x00\x00\x00\x00\x180000000\x02\x00\x00\x00\x180000000\x06\x00\x00\x00\x0d0000000\x08\x00\x00\x00\x00000"
