PHP recently underwent a bit of a security crisis when many media outlets disclosed the presence of a floating point bug. (RH bug here[1]) I feel I should bring attention to a PHP developer response[2] to this bug. Warning: There is a bit of emotion inside. They feel it is a gcc bug in FP handling, which seems (in my limited knowledge) to be accurate. The gcc fix was provided, not by changing default behavior, but by a compiler flag "-fexcess-precision=standard". Since this is a gcc bug (I believe bug is the right term) this could affect any gcc compiled code for the x86 arch that uses FP. Should the default gcc compiler flag set include the new flag?
