This shouldn't ever happen, and 1st 2 conditions never have.
The 3rd condition did happen, due to corrupt linkage due to a missing
align(8) in DYNDBG_CLASSMAP_USE, on the static struct allocation into
the __dyndbg_class_users section.
Not sure whether changing to _ONCE is appropriate - this is a
module-load activity, so it won't continuously spam syslog.
