            Bug ID: 16287
           Summary: ldbl-128 erfl 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

This bug report is from inspection of the ldbl-128 s_erfl.c, not from runtime
testing.  erfl is implemented to call __erfcl for arguments with absolute value
at least 1.0.  For large arguments where __erfcl underflows, this will result
in spurious exceptions when the result of erfl is very close to 1 and doesn't
underflow itself.
