--- Comment #2 from Christophe Lyon <clyon at gcc dot gnu.org> ---
Well, we have a nightly Jenkins job that builds GCC (from scratch) and runs
'make check' on ARM, AArch64, and x86 hosts, and from time to time we see
regression reports on the mentioned tests.
And the next run generally says those tests now pass.
For instance:
Test Run By tcwg-buildslave on Sat Feb 3 08:20:17 UTC 2018
Native configuration is armv8l-unknown-linux-gnueabihf

For libgo:context, there might be a real compiler bug though:
