Having said that, a port would be messy as IPF's own install scripts update src/sys/netinet, among other locations. That would be a big 'no', right there. Ports should never update kernel headers. If not for any other reason, because which kernel?. I regularly keep 2-3 different source trees of the kernel around, and build them from non-standard locations. Having to remember to run ipfilter_hack.sh on each of them before doing a successful build and ending up with kernel sources which are always 'unclean svn checkouts' would suck -- and I suspect I'm not the only one doing builds of kernels outside of /usr/src. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

If that means building with NO_CLEAN=yes then the problem is r249484.
It creates a symlink: ln -fs ../include ${DESTDIR}/usr/lib/include
But if ${DESTDIR}/usr/lib/include already exists it creates
${DESTDIR}/usr/include/include - ../include.
I'm thinking of reverting that commit.

If that means building with NO_CLEAN=yes then the problem is r249484.
It creates a symlink: ln -fs ../include ${DESTDIR}/usr/lib/include
But if ${DESTDIR}/usr/lib/include already exists it creates
${DESTDIR}/usr/include/include - ../include.
I'm thinking of reverting that commit.
Has this been sorted out? Not being able to buildworld with NO_CLEAN is a
bit of a pain.

Maybe -O3 overoptimizes regex in libc e.g., $ echo '#if @GNULIB_EUIDACCESS@' | sed 's/@GNULIB_EUIDACCESS@/0/' #if @GNULIB_EUIDACCESS@ $ echo 'xxx' | sed 's/xxx//' xxx How did you arrive at this result? 1/ chroot into poudriere jail for /head amd64 2/ echo CFLAGS+=-O3 /etc/make.conf 3/ make -j2 (in /usr/src/lib/libc) 4/ prepend LD_LIBRARY_PATH=. before sed(1) 5/ rebuild regcomp.o, regcomp.So with -O2 to confirm I have recompiled both libc and sed with -O3, but it works just fine here. Maybe -march=native is the clue, so which kind of CPU do you have? sse2 is available on amd64 even without -march=. But I can't reproduce the issue on i386 even with -march=native. To see what CPU llvm detects, try: tblgen -version | grep CPU Host CPU: penryn Note that -O3 turns on clang's vectorizer, so you might have run into an optimizer bug, or some kind of undefined behavior which now falls over. My luck is poor even with -O2 e.g., firefox20 crash on stackoverflow.com [New LWP 101222] [New Thread 801b02400 (LWP 101222)] [New Thread 81060e800 (LWP 101372 StreamTrans #1)] [New Thread 810ee8800 (LWP 101373 DOM Worker)] Program received signal SIGSEGV, Segmentation fault.
