I have come across an error that halts processing with the latest 
release. The following demonstrates this:

    \setuppagenumbering [location=]

    \starttext

      \dorecurse{36}{\dorecurse{19}{abc }}

      \startplacetable[location=split,title={Table}]
         \starttabulate[|p|p|]
         \HL
         \NC Heading \crlf
             heading
         \NC Heading \crlf
             heading
         \NC\AR
         \HL
         \NC abc \crlf
             abc
         \NC abc
         \NC\AR
         \NC abc \crlf
             abc
         \NC abc
         \NC\AR
         \NC abc \crlf
             abc
         \NC abc
         \NC\AR
         \NC abc \crlf
             abc
         \NC abc
         \NC\AR
         \HL
         \stoptabulate
         \stopplacetable

    \stoptext

while this version ends with the error : error (nodes): attempt to 
double-free rule node 55342, ignored

    \setuppagenumbering [location=]
    \starttext

      \dorecurse{37}{\dorecurse{19}{abc }}
