           Summary: (*SKIP) at the start offset may cause hanging
           Product: PCRE
           Version: 8.02
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
        AssignedTo: ph10@???
        ReportedBy: jay__tea@???
                CC: pcre-dev@???

The following were tested using mIRC v7.1's $regex() function:

String: abc
Regex: /b?(*SKIP)c/

Results in the client hanging, presumably awaiting a response from the PCRE
library.

String: bc
Regex: /b?(*SKIP)c/

Returns a successful match, as it should.

The following example also does not produce a hang:

String: a
Regex: /(*SKIP)bc/

Whereas this one does:

String: a
Regex: /(*SKIP)b/

I'm not sure if this issue is still present in PCRE v8.10 but I can't see
anything in the changelog about it.
