Yes I've seen that, I just use -w normally. It also happens with --sort
srcline. The column sizing code could probably be somewhat smarter and
always allow the last column to become as wide as needed. But that's
something that should be done separately; I don't think it belongs
into this patch.

No I didn't. Some generic issue, likely happening with srcline and
perhaps even objdump -S too. Find out with strace what file it is.
