Follow-up Comment #11, bug #15410 (project freeciv): That's precisely why there is a cast there... Dunno what's wrong there. Can you try to add a cast to _(void *)_ before _tslot_?

Follow-up Comment #12, bug #15410 (project freeciv): This seams like a bug of gcc...

Follow-up Comment #6, bug #15410 (project freeciv): I'd expect more warnings from a newer version, not fewer. Often yes, but sometimes warning situation detection gets more fine grained and warning is no longer outputted for completely safe constructs. I have not checked if it's the case here. Anyway, dereferencing type-punned pointer will break strict-aliasing rules happens far more with older gcc versions (I notice it often when cross-compiling to windows, MinGW version of gcc is 4.2.1) than newer. ___ Reply to this item at: http://gna.org/bugs/?15410 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
