Steps to reproduce:
- Create a new "text" data type and get the attached file (this would be the parent item)
- Configure a dependent item and set "preprocessing" to "regular expression"
- Input the following regular expression: 'node2(.|\n)*?rollupStatus": "(.*)"\n'
- Configure the output to be '\2'
Result:
As soon as data is received from a proxy by the server, it crashes (due to one of child processes crashing)
Logs show:

Expected:
Zabbix server properly handles the valid PCRE regex for preprocessing and does not crash
