This seems to come from dev-util/cvs-1.12.12-r4 being compiled with sys-devel/gcc-4.3.3, because: dev-util/kbuild-0.1.4 pulls in as dependencies dev-util/cvs-1.12.12-r4 and sys-devel/gettext-0.17 compiling all three with gcc 4.3.2-r3 works fine only gettext with 4.3.3 works fine only gettext and kbuild with 4.3.3 works fine compiling all three with 4.3.3 leads to the above error So this is probably something about porting cvs to gcc-4.3.3. I will look for suspicious compiler output in cvs.

Tray to disable fortify_source or -Wformat-security New thing in gcc 4.3.3
(In reply to comment #10) > Tray to disable fortify_source or -Wformat-security > New thing in gcc 4.3.3 > -Wno-format-security did not help, but setting -D_FORTIFY_SOURCE=1 (default seems to be -D_FORTIFY_SOURCE=2) for cvs worked fine.
Confirmed and working if I use -D_FORTIFY_SOURCE=1 in CVS Portage 2.2_rc23 (default/linux/x86/2008.0, gcc-4.3.3, glibc-2.9_p20081201-r1, 2.6.28-gentoo-r1-daedalus i686)
If I do not get it wrong this is basically a duplicate of #218567 (or #230849, which has been marked as dup of #218567). Patrick Lauer added a patch for #218567 today.
dev-util/cvs-1.12.12-r6 has been stable on all arches for quite a while, which should have fixed this issue. For details look at bug #218567. Closing this bug as it seems to be fixed. If anyone is still experiencing this problem, it is probably better to create a new bug report.
