[Gcl-devel] Re: [Axiom-developer] 2.7.0 reports

[Camm Maguire]

Greetings!  There is something wrong with sgc, I think minor.  One can
trigger and help debug if desired using the simple command (typep 0
'standard-object) in a fresh compiler::link'ed image interspersed with
calls to (si::gbc t) This is the lisp in build/i686.../bin/

I'll try to fix this soon.  In the meantime, the build appears to
progress with (si:sgc-on nil).  May I also suggest (setq
si::*disable-recompile* t) in the initial image for the time being.

Take care,
