Bug#435804: Segfaults during first sortie

[Trent W. Buck]

Package: warzone2100
Version: 2.1.0~0.svn1436-1
Severity: important

I can repeatedly cause a segfault thusly:

    - Choose "Single Player Campaign"
    - Choose "New Campaign"
    - Select four tanks by dragging left mouse button
    - Order tanks eastward by clicking east with left button.

Past the flashing blue oil, there is a gap in a north-south mountain
range.  After passing through this, tanks automatically engage a
handful of red-orange infantry units.  At this point, the segfault
occurs:

    $ warzone2100
    Segmentation fault
    $ warzone2100
    *** glibc detected *** warzone2100: malloc(): memory corruption (fast): 0x0000000007717830 ***

The tutorial map worked without problems.  I am using a Radeon 9000
GPU with the free radeon(4) driver, with direct rendering.  I edited
~/.warzone2100/config to change the screen size to 800x600 and to
disable fullscreen.
