My version is:
MiKTeX-MetaPost 2.4.1398 (0.641) (MiKTeX 2.4)

Which version is the latest?

What are "independent variables"? Is there anything I can do to use
less?
I thought all variables between beginfig and endfig are local and
cleared after the endfig, so the memory should be freed.

Sorry, I have no clue, what you are talking about. How can I regenerate
the .mem file?

> Hard to tell without your actual files.
I'll try to put something together which causes the error.
(In the original version, there is some stuff, I can't post here.)

Thanks for your help!
