            Bug ID: 18803
           Summary: [i386] hypot missing underflows
           Product: glibc
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
  Target Milestone: ---
              Host: i?86-*-*

The i386 version of hypot can sometimes miss underflow exceptions, e.g.:

Failure: hypot (-0x3.75bd8eea2718p-1028, -0x4p-1076): Exception "Underflow" not 
set
Failure: hypot (-0x3.75bd8eea271cp-1028, -0x4p-1076): Exception "Underflow" not 
set
