This needs to be fixed upstream if intended, or reverted if that was unintended. balage@makacs.duf.hu 2008-02-12 16:18:35 0000 Downgrading to 7.4-r1 works until upstream fixes it. fauli@gentoo.org 2008-02-12 18:09:07 0000 (In reply to comment #5) > Downgrading to 7.4-r1 works until upstream fixes it. And you get a security hole as bonus. fauli@gentoo.org 2008-02-12 19:01:04 0000 This has been reported upstream and is discussed there: http://bugs.exim.org/show_bug.cgi?id=664#c3 is the way to Nirvana...could someone with API breakage test the patch there? fauli@gentoo.org 2008-02-13 08:11:54 0000 -r1 with the upstream patch has been committed to stable, seems to work in my chroot. Thanks for the report. mike@nerone.org 2008-02-13 19:40:10 0000 Will -r1 break packages for those of us that have already recompiled everything that links to libpcre? No big deal, I can just recompile same again - just don't want to waste the time if it's not necessary. fauli@gentoo.org 2008-02-14 07:04:41 0000 (In reply to comment #9) > Will -r1 break packages for those of us that have already recompiled everything > that links to libpcre?

Just test it. :) grobian@gentoo.org 2008-02-15 17:21:24 0000 FYI: the patch breaks Darwin: error: only weak aliases are supported in this configuration
