            Bug ID: 46797
           Summary: 'ab' is a valid char constant; is an error with
                    -pedantic-errors
           Product: clang
           Version: 10.0
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C
          Assignee: unassignedclangbugs at nondot.org

The C standard says [Character constants clause]: The value of an integer
character constant containing more thane one character (e.g., 'ab') ... is
implementation defined.

clang with -pedantic-errors considers it an error.
