Hi Manu, This is in regards to your Comments for the gcc feature enhancement request, http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25702.

The other two were not in the Dragonfly code base, so he didn't comment on those. The 24 definite bugs have been corrected in Dragonfly. Paul Vixie corrected the bind bugs in the BIND8 sources and said thought this check would be a great compiler feature. I don't know if the bugs have been fixed in FreeBSD. I contacted [EMAIL PROTECTED] to make sure there were no security problems cause by these bugs and got no response. I didn't pursue the matter further after that. > > It really seems too noisy and with no clear way to avoid or workaround an > invalid warning. > This should be implemented in such a way that 'sizeof(ptr)' gets warning, but 'sizeof(char *)' doesn't. --mark -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25702
