[Opendnssec-user] ods-ksmutil key list --zone segfaults

[Jerry Lundström]

Hi Sander,

Looks like when the Mutex is destroyed is calls MutexFactory but it
doesn't check if there is an instance of the factory and it could have
been free'ed before the Mutex itself.

Try this patch to softhsm if you can:

 	}
 }
