[Freeciv-Dev] (PR#2935) SDL Client -- Fullscreen option

["Davide Pagnin via RT" <rt@xxxxxxxxxxxxxx>]

        Hi there!

In my experimental tries with the SDL Client, I've found another
problem, that Jason consider not common to every platform.

I've been able to successfully compile and run the sdl-client, both on
linux and Tru64 Unix 5.1A, but when I try to switch to fullscreen,
through the appropriate option, the client segfault.

I've isolated the problem to the togle_fullscreen_callback, inside
optiondlg.c file.

at line 237:241 there is:
  while (pModes_Rect[i]->w < Main.screen->w) {
    i++;
  }

On my linux system, before starting the cycle I get:
pModes_Rect[i]->w == 1024
Main.screen->w == 640

And when i became 1, the system segfault

On my Tru64 Unix alpha system, I get:
pModes_Rect[i]->w == 1280
Main.screen->w == 640

And when i became 1, the system segfault

I don't know what goes wrong.

If this can be of help, my linux system is:
Redhat 7.3
kernel 2.4.18-18.7.x
gcc 2.96-113
XFree86 4.2.0-8
gdm 2.2.5.4-1.ximian.25 (I use ximian gnome desktop)
SDL 1.2.4-1.ximian.3
