Do you see this `spike' in the DVI output also?  Alternatively, if you
call mf2pt1 as

  FONTFORGE=foo mf2pt1 --rounding=0.0001 <mf-font>   ,

do you see the irregularity if you open the font with fontforge?  This
would indicate a problem with the MF code.  Otherwise (and I believe
this is the cause), it's a bug in fontforge's intersection resolution
algorithm.  You might try the recent CVS version of fontforge which
has a lot of fixed issues.  Don't forget to pass `--enable-double' to
the `configure' script of fontforge.
