    There is some kind of bad interaction between
    DEFVST and purification.

    The file MAXTUL;MCL _UNDU_
    contains a script file of the lossage encountered.

    For a demo of the bug, try dumping out
    a macsyma compilation environment, like so:

    MAXTUL
    CL

    when it asks the question "(*PURE?)", reply T,
    and then watch things load, until it bombs.

    -gjc
This problem should be fixed in the new EXTEND, in the new LISP.  They should
be released shortly.
