Re: scheme closures: crash during garbage collection

[gregory benison]

I think there can be a solution to this issue without any big change in the way guile-gnome deals with refcounting and memory management. I am aiming for a substitute for scm_gc_protect_object() / scm_gc_unprotect_object() which has the same semantics but is safe to call during GC, and I think I have it.

My proposed fix for the garbage collection issue can be tested by
applying the attached patch file to the directory where gclosure.c
lives.
Here is a short code snippet that exercises the gc protection mechanism:

(use-modules (gnome gtk))
(define obj (make <gobject>))
(connect obj 'notify (lambda args 'ok))
(gc)
(set! obj #f)
(gc)
(gc)
