[metapost] metapost crashes?!

[Jaakko Luttinen]

I was adviced to ask for a help from this mailing list so here it goes.

My UML code crashes the mpost. The code below is just a clean version of what 
I'm actually trying to do, but the problem arises even with this code. If I 
comment out two class layoutings and drawings (e.g. V, X), the code works fine. 
How can this be? The code is similar for each class! To me, it seems like 
MetaUML can't handle this many classes. That can't be the reason, can it? 
 
I guess those layoutings are not necessary in this particular code, but the 
real code I'm working on needs at least a few layoutings before positioning. 
Don't think that could be the answer either.. 
 
The output is also at the end of this message. It doesn't have any errors. When 
the last line is printed, mpost hangs for a few seconds and then Windows gives 
this message and asks whether I want to send an error report: 
"mpost.exe has encountered a problem and needs to close. We are sorry for the 
inconvenience." 
 
I'm using Windows XP Home Edition. 
First line of output of "mpost -version": 
MiKTeX-MetaPost 2.4.1955 (0.901) (MiKTeX 2.4) 
First line of output of "latex -version": 
MiKTeX-e-TeX 2.4.1986 (2.2) (MiKTeX 2.4)

I appreciate all answers and help. I'm in a little hurry with this work, so the 
sooner the help comes the happier I am. =)
