After upgrading from 7.4.9 to 7.4.12, several MS SQL Database Query items went unsupported.

There appears to be a regression or change in handling multi-statement MSSQL batches. Executing these queries manually using isql still works fine
The queries stopped functioning immediately after the update (they still have data in Latest Data from before the upgrade).

Particular note was repeated few times in the logs:

[file:odbc.c,line:478] zbx_malloc: allocating 0 bytes. Please report this to Zabbix developers.
