Sigsegv-ing caused by a custom texture, here we are.

The subject should make sense of it, and I figure after having checked every viable resource, I should ask about it on the forums. This bigass link substitute is my plea for assistance to the mapping gods of srb2.

I think the actual cause of this sigseg is because 1.09.4 can't handle flats with transparency.

Alright, it seems like you have copies of the same map over and over for some reason. I will assume the top one is the most recent. Delete everything after the F_END lump and before the SCR01128 lump. Then delete everything after the SCR01128 lump. The paypal lump is not needed, and the MAP01D lump seems corrupt.

I suggest you make the last four lumps (F_START, GLASSIII, F_END, SCR01128) to be the first lumps in the WAD. The map lumps are usually the last lumps in a WAD.
