            Bug ID: 36479
           Summary: libc++'s <stdlib.h>, <math.h>, <cstdlib>, <cmath>
                    provide wrong overload sets for abs
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

libc++ does not implement the resolution of LWG issue 2192:

  https://cplusplus.github.io/LWG/issue2192

This results in the wrong value being produced for uses of abs() after only one
of math.h / stdlib.h is included.
