Checker: FORWARD_NULL (help)
File: base/src/source/blender/render/intern/source/texture.c
Function: do_lamp_tex
Description: Variable "co" tracked as NULL was dereferenced.

co was set to NULL at the beginning of the function and it could
possibly slip through all the logic above so lets test it before
we use it blindly.
