I did try the beta with that example and it worked, of course.  But if
I add a second \startC ... \stopC section, then it breaks.  For
example, this code (also attached as tadtest0.tex):

============================================================
\enabletrackers[buffers.visualize]

\starttext

\definetyping[C] % [option=C]
\setuptyping[C][escape=yes]

\startC
#include <stdio.h>
int main(){
    return 0;
    /BTEX{\em unreachedCode;}/ETEX
}
\stopC

\startC
printf("The second C segment doesn't work.\n");
\stopC

\stoptext
============================================================

Produces this output:

============================================================
