It is by-design according to the clang folks. They have expressed in interest in offering a knob to change this behavior, but I do not know the status of it. That said, I believe Xin's recent commit fixed the issue of adding an additional free. IMHO the compiler should also be able to optimize this case of free out. FWIW I have a very strong feeling of Déjà vu here: we have discussed this exact type of change before. -- Eitan Adler Source, Ports, Doc committer Bugmeister, Ports Security teams _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
