Doomsday Engine

Hi,

I have recently been testing a new PWAD that I designed (http://www.starfighter.acornarcade....doom.htm#rienzi) on various different Doom source ports. Doomsday does by far the best job of rendering it, but unfortunately consistently crashes with a segmentation fault at a particular location in the level. By judiciously modifying the WAD file I believe I have identified the cause as semi-transparent wall textures on double-sided linedefs (typically used for bars). This would also explain why Doomsday crashes in the same manner when I turn around 180 degrees at starting position of map 1 of the Doom 2 IWAD. If I remember correctly, there is an outside enclosure with bars behind the player's starting position.

I have attached the verbose doomsday.out log file produced by the game engine in the hope that this might help to diagnose the fault. As you can see, I was using Version 1.9.0-beta6.1 Mar 31 2009 (DGL) of Doomsday with the Doom 2 IWAD and no PWADs, with an Intel Cantiga v2.0.0 (build 7.15.10.1576) as the OpenGL renderer. My machine is a recently-purchased Dell Inspiron 1545-5713 laptop.

I really hope it might be possible to fix this problem because the Doomsday Engine looks amazingly nice!
