--- Comment #8 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- It's not correct to use flag_signaling_nans for a fix. flag_signaling_nans is only for cases where a bit-pattern for a signaling NaN is interpreted as a floating-point value. It's not where a struct or union element has floating-point type but is never interpreted as a value of that type, just the whole aggregate copied. It's completely valid without flag_signaling_nans to copy a struct that happens to have such a bit pattern. Does the patch (without flag_signaling_nans) help with the bug 58416 case or not?
