CFLAGS="-O3 -march=pentium4 -pipe -fomit-frame-pointer" re-compile with sane CFLAGS please.
(In reply to comment #0) I had the same problem here. After some testing - all of no result - I've switched back from O3 to O2 because this was one of the differences betweeen my other installation where clamd was working. Now it's working again, so obviously -O3 is breaking clamd. Maybe the ebuild should filter the O3 compiler flag.
(In reply to comment #2) > Now it's working again, so obviously -O3 is breaking clamd. Maybe the ebuild > should filter the O3 compiler flag. This would seem to be a slightly evil fix. Maybe the ebuild can ewarn users about CFLAGS=-03 Also, most people running clamd on serverish systems such as mailservers (using clamav-milter, etc.) should not be using CFLAGS=-03 ;-)
(In reply to comment #3) > This would seem to be a slightly evil fix. Maybe the ebuild can ewarn users > about CFLAGS=-03 -O3 is unsupported. If you like to use it, then fix the bugs caused by doing so yourself. There's nothing to fix for us here. > Also, most people running clamd on serverish systems such as mailservers (using > clamav-milter, etc.) should not be using CFLAGS=-03 ;-) > It's not like they "should not", they wouldn't do so.

Sorry. Problem solved: The last time carelessly assembled.
