             Bug #: 13889
           Summary: expl (709.75) wrongly overflows for ldbl-128ibm
           Product: glibc
           Version: 2.15
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jsm28@gcc.gnu.org
                CC: sjmunroe@us.ibm.com
    Classification: Unclassified
              Host: powerpc*-*-*


For powerpc-linux-gnu, expl (709.75) wrongly returns infinity instead of the
correct finite value.  exp (709.75) correctly returns a finite value slightly
below DBL_MAX.

--- Comment #1 from Adhemerval Zanella Netto <azanella at linux dot vnet.ibm.com> 2012-04-18 12:42:40 UTC ---
Current code check if input won't generate overflow, but it seems the current
value check (709.08956571282405153382846025171462914L) is less than logl
(LDBL_MAX). I believe this value should be adjusted to higher one,
709.78271289338399678773454114190492789L.
