Greetings!  Thanks for this work!

I ran into a few of these too.  They only appear under GCL when the
file in question is loaded from source (i.e. interpreted), or compiled
with safety turned on.  GCL has the ability to bypass these checks for
verified code for the purposes of speed, and this appears to be the
default setting in the axiom build.  I don't know if the axiom source
is setting this explicitly or not.  I'm trying a build now with the
default safety in saved_gcl turned on -- if the axiom source does not
turn it off, this should assist greatly in debugging.  Once everything
works, we should turn it off again to maximize performance. Even
debugsys appears to load compiled code, currently compiled with no
safety checks, from the autoload directory.

I'm using (proclaim '(optimize (safety 3))).  One can check the values
with (compiler::print-compiler-info).

Take care,
