Unfortunately the netbsd-10 branch has been broken over the last weekend. A defective pullup (https://releng.netbsd.org/cgi-bin/req-10.cgi?show=1380) was processed on Fri, 23 Oct 2026 16:07:43 UTC, which broke all multi-threaded programs.
The breakage was not immediately obvious (build worked fine, system booted multi-user w/o any signs of problems for most setups). When the issue was identified it was easy to fix, so we did not back out the broken change, but instead fixed it. The fix landed on Mon, 26 Oct 2026 06:06:21 UTC. The "latest" build from the daily builds has the fix. If you updated you netbsd-10 setup between those two times, please update again! Sorry for the fallout. Martin
