VERY important bugs found

[alejandro-colomar]

• When playing, if I resize the terminal to be smaller than the board, segmentation fault is produced.
• If I start the game in a terminal smaller than the numbers I introduce for the size, the system hangs really bad. I had to use tty3 to init 6. (Killing -9 freesweep didn't help).

Using the version packaged with Debian stretch (stable), which is 0.90-3+b1

I have just packaged version 1.0.1 for Debian and I can still reproduce this issue. However on my Debian stable system an error message is printed and I don't experience that the system hangs.

***Segmentation Fault detected. Cleaning up....

[alejandro-colomar]

I did it again:

In a gnome terminal:

$ su
# apt-get purge freesweep
# apt-get install freesweep
# exit
$ freesweep

resize the terminal as small as I can, and... gnome is unrecoverable. kill -9 freesweep or the gnome terminal, or even the gnome shell doesn't work. Just init 6. (from tty3)

That's the backtrace I get when making the terminal window really small:
