Since a few weeks ago every program that uses meinproc during emerge-phase failes to build. Examples for affected programs would be k3b or kile. After asking around in Gentoo Forums and KDE-Bugzilla didn't provide any solution (one KDE-dev more or less told me that i'm f***ed because we use gentoo here) i thought it's time to file a bug here. E.g this is what i get when i try to emerge kile: emerge kile ... Making all in doc make[2]: Entering directory `/var/tmp/portage/app-editors/kile-2.0/work/kile-2.0 /doc' /usr/kde/3.5/bin/meinproc --check --cache index.cache.bz2 ./index.docbook /bin/sh: line 1: 18841 Segmentation fault /usr/kde/3.5/bin/meinproc --check --cache index.cache.bz2 ./index.docbook make[2]: *** [index.cache.bz2] Error 139 make[2]: Leaving directory `/var/tmp/portage/app-editors/kile-2.0/work/kile-2.0/ doc' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/app-editors/kile-2.0/work/kile-2.0' make: *** [all] Error 2 ... So i enabled debugging symbols and reemerged kdelibs, libxml, libz and glibc such that i get useful output from gdb. If i run gdb using the command '/usr/kde/3.5/bin/meinproc --check --cache index.cache.bz2 ./index.docbook' i get this (ouput including backtrace): (gdb) run --check --cache index.cache.bz2 ./index.docbook Starting program: /usr/kde/3.5/bin/meinproc --check --cache index.cache.bz2 ./in dex.docbook Failed to read a valid object file image from memory.

*** Bug 217608 has been marked as a duplicate of this bug. ***
Local problem ( http://bugs.kde.org/160154 ). -funroll-loops shouldn't be in your global CFLAGS,CXXFLAGS at all -fomit-frame-pointer makes backtraces useless on x86.
