Fedora 27 mass rebuild at risk
We currently have an invalid IFUNC resolver in libgcc.a on POWER
(rhbz#1467526). glibc in rawhide recently started linking that into the
library and there are significant problems with that (rhbz#1467518).
I'll be on PTO next week, and it does not seem likely that this is going
to be resolved upstream before that. If upstream (both glibc GCC are
involved) don't come up with a solution, I'm not sure
If we downgrade glibc to 2.25 in rawhide, we will have to rebuild at
least the following packages right after that because they have a
GLIBC_2.26 symbol version dependency:
inn-2.6.1-6.fc27.src.rpm
remctl-3.13-4.fc27.src.rpm
sudo-1.8.20p2-1.fc27.src.rpm
tmux-2.5-1.fc27.src.rpm
unbound-1.6.4-1.fc27.src.rpm
xorg-x11-server-1.19.3-6.fc27.src.rpm
Besides the glibc downgrade, I'm not aware of anything else we could do
to get ready for the mass rebuild in time.
Thanks,
Florian
