Just got hit by this bug (v. 0.995 rev. D):

! Extended mathchar used as mathchar (2097151).

l.277 where $\vec{u}
                     _1 = (u_1,w)$ is the velocity of the fluid,  
together wit...

where \vec had been redefined to use \bm from the bm package:

\renewcommand{\vec}[1]{\bm{#1}}

The above was with CM fonts in XeLaTeX, not using fontspec (just  
xunicode). In any case, building XeTeX from the latest source code  
(downloaded tonight from <http://scripts.sil.org/svn-view/xetex/ 
TRUNK.tar.gz?view=tar>) does indeed fix the issue.
