I broke down the code as much as I could and found out the following:

In one of my c-files I used the following code:

Code:
VIEW* ShaftView = {
	bmap = "#64x64x14";
	material = mtlShaftDepth;
	flags = SHOW|NOFLAG1;
}



When I remove the SHOW flag like this:

Code:
VIEW* ShaftView = {
	bmap = "#64x64x14";
	material = mtlShaftDepth;
	flags = NOFLAG1;
}



the engine crash is gone.

Is it wrong to use the SHOW flag in this case???
