--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-03-10 10:22:48 UTC --- Thanks for the analysis. I knew about the difference between signed and unsigned, makes sense. Not knowing in detail the internals of the optimization the puzzling bit is that types wider than unsigned int already work fine. The problem seems fixable, somehow ;)
