Simple check of the item "net.udp.service[{$BOOM}]" or similar where {$BOOM} has a value ",\" causes server/proxy to crash because return value of parse_item_key() is not checked in get_value_simple().
Discovered it myself "in the wild", but credits should go to Coverity, because it reported it long before me as CID 118898.
Just for catching duplicates:
