------- Comment #6 from paolo dot carlini at oracle dot com 2010-02-27 23:45 ------- It's harmless for sure. But certainly you don't want to build like that unless you are debugging (and then you should add -g, of course), because you are disabling most of the optimizations, exactly like -O0. Performance-wise, the library is unusable.
