A clear and concise description of what the bug is.

In the options menu: display options/anisotropic filter, if you scroll through the options, eventually the game will crash when you get to item 0, "default":

OptionValue "Anisotropy"
{
	0, "$OPTVAL_DEFAULT"
	1, "$OPTVAL_OFF"
	2, "$OPTVAL_2X"
	4, "$OPTVAL_4X"
	8, "$OPTVAL_8X"
	16, "$OPTVAL_16X"
}

You can scroll through the options in either direction. So it will go 8x, 16x, crash or 8x, 4x, 2x, off, crash.

4. press the left or right buttons to scroll through the choices
5. when the choice comes around to option 0, the game will (probably) crash.

Default is the same as OFF. So why have an OFF anyway ?

I checked this with Doom2.wad, map01, positioned on sector 7, looking north to the ceiling of sector 52.

This is in uzdoom.pk3, which makes more sense ...

OptionValue "Anisotropy"
{
1, "$OPTVAL_OFF"
2, "$OPTVAL_2X"
4, "$OPTVAL_4X"
8, "$OPTVAL_8X"
16, "$OPTVAL_16X"
}

Update ... The now defunct vkdoom had the default setting. I'm guessing it got transferred across to gzdoom ...
