Hi,

the following example causes

1) strange message: “invalid \starttext ... \stoptext structure” and

2) !LuaTeX error: PDF inclusion: file has changed 'Hga-typeset-buffer-001.pdf'
   ==> Fatal error occurred, no output PDF file produced!

\starttext
  \startbuffer [foo]
    foo
  \stopbuffer
  \typesetbuffer [foo]

  \startbuffer [foo]
    foo
  \stopbuffer
  \typesetbuffer [foo]
\stoptext

Marco

i uploaded a fix (some additional checking on redefining such buffers) 
.. the backend keeps the file open (which is where the message comes from)

\starttext

     \startbuffer [foo]
         \startTEXpage
             \input tufte
         \stopTEXpage
     \stopbuffer

     \dorecurse{20} {
         \typesetbuffer [foo] [width=\textwidth] \blank
     }

     \startbuffer [foo]
         \startTEXpage
             \input ward
         \stopTEXpage
     \stopbuffer

     \dorecurse{20} {
         \typesetbuffer [foo] [width=\textwidth] \blank
     }

\stoptext
