    Description

      Steps to reproduce:

      1. Zabbix Agent2 service process on windows 2012 crashing without any log or eventlog traces even in DEBUG mode, id the agent is configured to execute external UserParameter script. 
      2. The crash occurs cca after 5-20 minutes of Zabbix Agent 2 run, at least some data is sent into Zabbix Sever before the agent 2 crashes.
      3. In our environment, the powershell script for Hyper-V monitoring (https://share.zabbix.com/virtualization/hyper-v/template-microsoft-hyper-v-host) has been triggered by Zabbix Agent2 in active mode.
      4. Zabbix Agent2 on other windows servers without running UserParameter script works well
      5. We tested agent 2 versions 5.0.8, 5.0.10 and 5.0.11 - every version is affected by this bug.
      6. When downgraded to Zabbix Agent 1 (5.0.11) the agent 1 with forementioned powershell script works flawless.

      Result:
      Zabbix agent2 is crashed
