Hello all,

In the example below, I mean for a gray box with rounded corners to be
placed behind \startC ... \stopC blocks. This example compiles properly on
Linux with the latest ConTeXt beta and LuaTeX synced from the minimals just
minutes ago.

On Windows, also updated from minimals this morning, I get the following
error and no text background:

mplib           : initializing instance 'metafun' using format 'metafun'
mplib           : loading 'metafun.mp' from
'C:/context/tex/texmf-cache/luatex-c
