Yeah, the version from my ConTeXt Minimals does not crash either.

To reproduce the crash: download the source tarball from superlec.fr, 
build it and replace the mpost executable in the TeX Live 2009 
distribution. This is what I have done. Of course, I am missing 
something here.

TEX is set to etex in texmf.cnf, but MPXCOMMAND does not occur anywhere. 
This is the output:

mpost bug.mp
This is MetaPost, version 1.502 (kpathsea version 6.0.0)
(mpost.mp (/usr/local/texlive/2009/texmf-dist/metapost/base/plain.mp
Preloading the plain mem file, version 1.004)) (./bug.mp

(/usr/local/texlive/2009/texmf-dist/metapost/base/string.mp)
(/usr/local/texlive/2009/texmf-dist/metapost/base/texnum.mpSegmentation 
fault

Anyway, I can revert to mpost 1.211 in TeX Live and use 1.502 from 
ConTeXt Minimals, so this problem is not so serious for me.
