Steps to reproduce:
Configure the Log item to monitor a log file as follows:
log[/Library/FileMaker Server/Logs/Event.log,Warning]
The Zabbix Agent crashes every time this command is run.
Here is the crash log:

Side Notes:
- The crash only happens with log[], not with log.count[].
- If the regex field is left empty, the crash doesn't happen and the item works as expected.
- PCRE is installed on the Mac.
