[L4D2] Segmentation fault in dx9 translator

[gudvinr]

I ran into Left 4 Dead 2 process failing with SIGSEGV on Blood Harvest (Versus mode).
I have couple of campaign addons enabled and addon for replacing Infected shader with VertexLitGeneric for CI from L4D1 to workaround #3403.

I got the same crash at the same address today. Now it was Swamp Fever on official dedicated server (again, Versus mode). Since my addon for shader replacement only used for CI from L4D1 I am pretty sure it isn't the reason.

Same thing happened today in Versus mode at second chapter of Passing campaign.
