I get a crash (double free) with:

    echo '\endinput \end ' | context --pipe

and I get a 'normal' Fatal error occurred with:

   echo '\\endinput \\end' | context --pipe

and I think that solves that bit of the mystery.

Now for that double-free:

   echo '\tracingall \endinput \end ' | context --pipe

ends with:

It probably crashes because in context the \end code and the \endinput
code interfere with eachother. You get the same crash if you create a
simple input file with just that same line, and the crash goes away if
you put \endinput and \end on separate lines, and as far as I can tell,
context always crashes if \endinput and \end/\stoptext are on the same
line.

Best wishes,
