            Bug ID: 16314
           Summary: hypot spurious underflows
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

On x86_64, hypot (0x1.23456789abcdep-500, 0x1.23456789abcdfp-500) raises a
spurious underflow exception.  Although squaring either argument does not
underflow, products involving low parts of arguments, as computed in the hypot
implementation, do underflow.
