I see this as well on ~arm. Interestingly the build succeeds for python2.7 but fails for 3.6. MAKEOPTS=-j1 does resolve it for python3.6.
Same here on ~amd64 and dev-python/zstandard-0.12.0, works with MAKEOPTS=-j1.
Yes, still happening with 0.12.0.
I speculate that if we handle the bundled zstd bug, the race condition can probably be solved.
