crash in pixelshader.c

Hi, it crashes now again, see attached log. Ivan, this is caused by a patch by
you. Following patch fixes it but i don't know if it's really correct. Ivan ,
could you have a look at it? I think curOpcode is NULL on my computer, which
seems to cause the crash. What should happen in the function if this happens?
Thanks.
