\startalign broken in the lastest beta?

\startalign broken in the lastest beta?

[Longmin Wang]

Dear Hans, 

Please see the example below, which is not correctly compiled in the
lastest beta. 

\starttext
\startformula \startalign
 \NC v \NC = u + at \NR
 \NC h \NC= ut + \frac12 gt^2 \NR
\stopalign \stopformula
\stoptext

This is an engine error.

  \halign{$#$&$#$\cr u&\cr}\bye

Will be fixed soon, I hope.

Best wishes,
Taco

Now that I fixed it, I suspect there is an even shorter
minimal file possible, but I 've fixed it already so
I can't try that any more. This might also do the trick:

   \hbox{$x$$$}\bye

(but it needs to be run with context)

Anyway, the fix in luatex svn already. I expect to release
0.39 on wednesday.

Best wishes,
Taco
