HOST.CONN doesn't work in global scripts

global scripts don't seem to work with HOST.CONN macro anymore. tried with agent and snmp interfaces and ip specified for them.

debuglevel 4 gives :

In substitute_simple_macros() data:'/bin/ping -c 3

'
End substitute_simple_macros() data:'/bin/ping -c 3 UNKNOWN 2>&1'
In zbx_execute_script()
In zbx_popen() command:'/bin/ping -c 3 UNKNOWN 2>&1'
End of zbx_popen():7
