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:
============================================================
