Subject: mesa: Fix array out-of-bounds access by _mesa_TexGend.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b82757880545f8bce471ba8f13c16998888cd4b5;p=mesa.git

mesa: Fix array out-of-bounds access by _mesa_TexGend.

_mesa_TexGend calls _mesa_TexGenfv, which uses the params argument
as an array.
