Message-ID: <E1BbWNv-0001Eh-Ms@fencepost.gnu.org> (raw)

Since old_value is not a lisp object here,
we would need to fix (hack) GC like this:
for (bind = specpdl; bind != specpdl_ptr; bind++)
{
mark_object (bind->symbol);
if (bind->func != safe_alloca_unwind)
mark_object (bind->old_value);
}
Or else use make_save_value to convert it to a clean Lisp object.
Then GC won't need changing.
