Steps to reproduce:
- Create log item with this regex:
(\d{4}-\d{2}-\d{2}\s+\d{2}:\d{2}:\d{2}\.\d{2}\s+\w+\s+)Error:.+((\r\n|\r|\n)\1{1}.+){0,}
- Wait for the item to become unsupported with "cannot compile regular expression" error
Result:
Item configuration:
Agent log:
11880:20181015:120836.677 In process_log() filename:'d:\fake-log\fake.log' lastlogsize:0 mtime:0

11880:20181015:120836.678 active check "log["d:\fake-log\fake.log","(\d{4}-\d{2}-\d{2}\s+\d{2}:\d{2}:\d{2}\.\d{2}\s+\w+\s+)Error:.+((\r\n|\r|\n)\1{1}.+){0,}","UTF-16"]" is not supported: cannot compile regular expression

Expected:
Log item should be able to use regex and parse log file.
Notes
This regex is interned to parse multi-line log messages and it's works in Zabbix regex tester (Administration -> General -> Regular Expressions) and pcre2test tool.
