I installed texlive 2010 and it works correctly. Note that mpost
form 2010 compiles this function without need of double option.
It has none anyhow.

I very much hope that you can fix this. I have used TeX and its associated
stuff since about the beginning and this is the first update 
incompatibility that
I have encountered. Luckily, just before posting the paper with that figure
in it, I caught the error.
