Confirmed, using RC3 (icl) on WinXP P3 800 with 512MB.
Note that ground fog will also turn the sky red like this if fog_alt is 0.
Seems something goes wrong when 0, or the equivalent to zero, is used. Your
example shows the plane primitive to be a factor. How one declaration works
right and the other does not sure is peculiar. Just a personal observation.
It also seems to be related to multiplication, as you said.
