_______________________________________________________
Details:
This has been first noticed by NetBSD original porter, and been fixed in
pkgsrc. It happens on OpenBSD too. To reproduce, start a simple game, make an
explosion (dynamite, whatever), wormux segfaults in src/map/tileitem.cpp:
map/tileitem.cpp:266: Missed assertion "tile_lenght > 0".
zsh: segmentation fault (core dumped) wormux
Partial backtrace:

The attached patch against 0.8.0 (taken originally from
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/games/wormux/patches/patch-aa?rev=1.1.1.1&content-type=text/x-cvsweb-markup
and backported to 0.8.0 on OpenBSD) seems to fix the issue.
