[Bug libc/15522] New: strtod ("nan(N)") returning a sNaN in some cases


http://sourceware.org/bugzilla/show_bug.cgi?id=15522

             Bug #: 15522
           Summary: strtod ("nan(N)") returning a sNaN in some cases
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: tschwinge@sourceware.org
        ReportedBy: tschwinge@sourceware.org
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


strtod ("nan(N)") (and likewise for the other float types) exhibits wrong
behavior such that for architectures defining
HIGH_ORDER_BIT_IS_SET_FOR_SNAN, a sNaN is returned for N = 0, and for
other architectures a sNaN is returned for positive integral N != 0.
