Subject: monster-masher: Segfaults after starting the game

Date: Sat, 30 Jul 2011 12:04:38 +0200

Package: monster-masher
Version: 1.8.1-3
Severity: important

I started up the game, looked at the introduction, pressed "New game",
selected 1 player and then it segfaulted.

>From the core file I see this:

Well, not very useful.

The next time I tried, the game ran fine. But then I didn't look through
the introduction. So, I tried again: the game reproducably segfaults
when first watching the introduction and then starting a new game.

tags 636014 + patch
quit

It's memory corruption when Intro.update calls intro_finished(),
and intro_finished deletes the Intro.

The attached patch is a workaround rather than a fix, but probably
sufficient to prevent the crash on all architectures.
