1. Create item with history storage period={$MACRO}
2. Set macro {$MACRO}=1dd
3. Start Zabbix server
4. Execute housekeeper manually:

 ./sbin/zabbix_server -R housekeeper_execute 

Expected:
Item must become unsupported (possibly during configuration sync) or there should be clear indication to user that error occurred.

Actual:
No housekeeping will be performed and no warnings will show up in the log.
If log level is increased to debug, then it's possible to see

invalid history storage '1dd' for itemid '28289'
