           Summary: Accepting wrong posix class name
           Product: PCRE
           Version: N/A
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
        AssignedTo: ph10@???
        ReportedBy: felipensp@???
                CC: pcre-dev@???

I'd noted that check_posix_name() not is called when in class name appears an
escape, or space.

See the tests:

re> /[[:foo:]]/
Failed: unknown POSIX class name at offset 3

OK!

re> /[[:f\oo:]]/
data> [[:foo:]]
0: :]

and

re> /[[: :]]/
data> /[[::]]/
0: :]


Odd...


Is it a normal behavior? Althrough accepts a illegal class name, match just the
end too.


Regards,
Felipe Pena.
