An example that triggers this bug (selected from cp.c (coreutils v8.25)
compiled by gcc5.4 on x64 ubuntu 16.04)

A "-a" argument can affect whether gas will choose to use "JMP 8-bit" or "JMP
32-bit" in an output object file.

These are the commands to regenerate this bug:

$ as -o cp.o cp.s
$ as -a=cp.lst -o cp.a.o cp.s
$ objdump -d cp.o > cp.txt
$ objdump -d cp.a.o > cp.a.txt
$ diff cp.txt cp.a.txt
