I think the ebuild should check that the /sbin/grub binary works. It dumps core on me but gdb cannot find any symbols in it. I tried USE="static -ncurses" but that did not help. Starting /sbin/grub gives me the grub shell, but during quit I get a core dump. I tried gcc-4.6.3 and 4.7.4 with no change. Maybe the -Os compiler flag is too aggressive or buggy? Either way, my C{XX}FLAGS are ignored so I can't do much at the moment. # emerge --info WARNING: One or more repositories have missing repo_name entries: /var/lib/layman/profiles/repo_name NOTE: Each repo_name entry should be a plain text file containing a unique name for the repository on the first line. #

So, the issue with gcc caused by -O2 in ${WORKDIR}/grub-0.97/config.status: S["GRUB_CFLAGS"]="-O2 -fno-strict-aliasing" Grub crashes with any of [-O1,-O2,-Os]. This happens with x86_64-pc-linux-gnu-4.9.3 but not with x86_64-pc-linux-gnu-4.7.4 nor x86_64-pc-linux-gnu-4.8.5.
So, if commands fail during pkg_postinst it can actually be worse to die rather than to continue, as there's no rolling back at that point. The actual issue as to why it dies is bug 564890 , so I'm going to mark this one as a duplicate. *** This bug has been marked as a duplicate of bug 564890 ***
