            Bug ID: 24018
           Summary: Optional warning for octal numbers
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

People don't expect 010 == 8 to be true. People rarely use octal numbers, the
most frequent (only?) use case appears to be POSIX file permissions. People do
sometimes prefix decimal numbers with a 0 by mistake..
Could you add an optional warning for such cases?
