--- Comment #11 from Nicola Pero <nicola at gcc dot gnu.org> 2011-03-19 01:24:47 UTC --- Having looked at some of the warnings generated in GNUstep if you compile with -fstrict-aliasing, they seem to be C warnings with little relevance to Objective-C (they mostly seem to be due to casting to (void **)). So on that side (the warnings) I guess I am inclined to join Mike and become skeptical of this issue. Unless the original report was that using -fstrict-aliasing would miscompile Objective-C code ? We need an example though. Thanks
