Crash to Desktop Upon Map Rendering

[rmod8]

Details

I'm working on a new map which uses multiple high-polygon models for the 3D Skybox. Testing earlier during the project lead with no problems besides a hit to the framerate. After 2 days of brushwork on the main map, I compiled with the 3D skybox and lead to a crash. Compiling without the models leads to a working map, but compiling with the 3D Skybox models leads to an immediate crash, no dialog or anything. The dump indicates the process is trying to access memory it does not have permission to access.

The map compiles properlly with no leaks or any budget issues.

I am using Slammin' Source Tools' VBSP, VVIS, and VRAD for ambient occulsion. I have not seen any issues with using those compilers with Garry's Mod Before. The map was compiled with VBSP and VVIS, but with VRAD disabled to save time testing the map.

console.log indicates no information, besides the standard information given out when loading maps. From the behaviour seen in the console and loading, it seems to be an issue with rendering, which makes sense.

Link to the dump

It would be nice if this could be fixed, but I have to be honest and say the map's 3D skybox models are too expensive anyway.

Steps to reproduce

(This is a Minecraft map, sorry!) Running gm_bbqbay_revival_withSkybox will crash the game, running the version without the skybox (gm_bbqbay_revival_noSkybox) will not.
