--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> --- Please stop putting inaccurate "Compiler flags" lines in your bug reports. There are multiple additional options you are using that change the generated code. Including, but not limited to -fwrapv and -fno-strict-aliasing. I've stumbled over this issue repeatedly already and I suspect others will do so as well. We appreciate you trying to summarize the options you think are important, but it's better to just give the command line you use rather than tryign to give an (sometimes inaccurate) summary.
