OK, preliminary equalp hashing is in CVS head.  Are you comfortable
compiling from there, or do you prefer to wait for Debian package
migration.  I still have a few other items that need going in before I
tag t6 and make another Debian upload.

Thank you for this.  This is indeed a reproducible bug.  It will
require a radical change which I'm hesitatnt to attempt at this
moment.  Basically, GCL writes an initialization lisp code sequence
at the end of each compiled file.  It reads the code, loads the
object, identifies the objects in the code with their addresses in the
loaded binary, then evaluates the forms.  What it needs to do is read
one form at a time, identify, and eval, etc.  You make and use the
package in the same initialization sequence.  A standard workaround is
to put all your defpackage statements in a separate file which is
loaded first.  Is this doable for you?

We will eventually get to this, but it would appear that other
priorities are more pressing at the moment.  Please let me know how
this might impact your work -- that is how the pririties are set in
the first place :-).

Take care,
