llSetPrimitiveParams

When I try to set PRIM_COLOR and PRIM_TEXTURE of two faces of a prim in one single llSetPrimitiveParams command, I get... well, weird results.
When using two seperate llSetPrimitiveParams commands, one for setting the color and one for setting the texture, it works fine. But this causes yet another 0.2 second delay. What that !&&%$ delay shall be good for in this command, god - pardon, the Lindens - only knows.

Am I doing something wrong, or is it simply broken?

working:
CODE
llSetPrimitiveParams([PRIM_COLOR, 5, <1.0, 1.0, 1.0>, 1.0,
                      PRIM_COLOR, 4, <1.0, 0.0, 0.0>, 1.0,
                     ]);

llSetPrimitiveParams([PRIM_TEXTURE, 4, tex_one, <0.1, 0.1, 0.0>, <-0.553, 0.450, 0.0>, 0.0,
                      PRIM_TEXTURE, 5, tex_two, <3.0, 1.0, 0.0>, <0.0, 0.0, 0.0>, 0.0
                     ]);


NOT working:
CODE
llSetPrimitiveParams([PRIM_COLOR, 5, <1.0, 1.0, 1.0>, 1.0,
                      PRIM_COLOR, 4, <1.0, 0.0, 0.0>, 1.0,
                      PRIM_TEXTURE, 4, tex_one, <0.1, 0.1, 0.0>, <-0.553, 0.450, 0.0>, 0.0,
                      PRIM_TEXTURE, 5, tex_two, <3.0, 1.0, 0.0>, <0.0, 0.0, 0.0>, 0.0
                     ]);

Sorry, I really can't see what the problem is here. However, you could put the two working calls in two other scripts and call them via llLinkMessage with LINK_THIS, so each script will carry a .2 sec penalty. A bonus is that there is no time penalty in your main script.

Someone else might offer a better suggestion?

I think I've met this bug before. Have you tried reversing the order of the parameters? i.e. put the PRIM_TEXTURE params before the PRIM_COLOR params. I can't clearly remember the case where I had this issue, but I think changing the order around helped.

LOL
I shuffled them a bit and that really did the trick.
Thank you very much, Kermitt!
Full of... surprises, that LSL :)

Someone should check if this bug exists in the 1.13.4.3 preview with llSetLinkPrimitiveParams.

Should anyone have the same problem, this worked for me:
CODE
llSetPrimitiveParams([PRIM_COLOR, ALL_SIDES, <1.0, 1.0, 1.0>, 1.0,
                      PRIM_TEXTURE, 5, tex_one, <3.0, 1.0, 0.0>, <0.0, 0.0, 0.0>, 0.0,
                      PRIM_COLOR, 4, color_one, 1.0,
                      PRIM_TEXTURE, 4, tex_two, <0.1, 0.1, 0.0>, <0.0, 0.0, 0.0>, 0.0
                     ]);
