BS1 Unexpected segmentation fault

Reported by: SF/jellby Owned by: eriktorbjorn
Priority: normal Component: Engine: Sword1
Keywords: Cc:
Game: Broken Sword 1

Description

I'm getting somewhat random but frequent segmentation faults in
Broken Sword 1. I attach a savegame in the Irish bar. Whenever I try
to talk to the guy with glasses I get a segfault. Sometimes it's right
after he says "What's the problem?", sometimes it's as soon as I
press the green arrow (to quit the conversation), sometimes it's
when I try to talk to him the second time.

My system:
Mandrake 10.1
ScummVM 0.8.0CVS (May 1 2005 10:56:29)
Features compiled in: Vorbis FLAC MP3 ALSA zLib MPEG2

PS This doesn't appear to be a sound issue, it happens even with
sound, music and video files out of sight.

This one I can reproduce. I have no idea what's causing it,
though.

Aha! I see the problem. It's actually not a Broken Sword 1
bug at all, it's a buffer overflow in the SDL backend's
"dirty rectangle" handling. The Broken Sword games are
probably the ones most likely to trigger it since they tend
to mark a lot of smaller rectangles as dirty, rather than a
few larger ones.

Fixed in CVS.
