Mikael Morin <mikael at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mikael at gcc dot gnu.org --- Comment #1 from Mikael Morin <mikael at gcc dot gnu.org> 2012-08-17 16:58:54 UTC --- As always, that's a nice to have feature, but without a thorough control flow/value range/whatever analysis, it would either give a warning in trivial cases only or have many false positives. A warning for b) makes sense to me; for the others: a) I don't see what prevents a function from returning a short lived pointer c) d) The pointer is globally accessible, so I'm not so sure how it could be nullified or re-associated.
