#2942: header cache is still not safe Comment (by pdmef): (In [b9ac445b035b]) Prevent some pointers of 'struct body' being saved to hcache This addresses the hcache safety issue but maybe doesn't fix it completely, see #2942. This also prevents mutt from crashing when using a hcache that was synced when syncing the mailbox (updating changed and fully-parsed messages). -- Ticket URL: <http://dev.mutt.org/trac/ticket/2942#comment:2>
