When wget is downloading a file, a segfault happens when resizing the terminal
small enough to only have few columns visible.

Steps to reproduce:

1. download a file with wget:

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.6.2.tar.xz

2. resize the terminal with the mouse to only show a few columns
3. a segfault happens

I'm running wget 1.18 in archlinux under xfce.
I've faced the segfault with xterm, urxvt and xfce4-terminal.

uname -a: Linux cartman 4.5.4-1-ARCH #1 SMP PREEMPT Wed May 11 22:21:28 CEST
2016 x86_64 GNU/Linux

You can find the way wget has been compiled here:


I've attached the output of strace.
