I would like to bring attention to this bug report:
WebAssembly is getting quite some attention in the 8.0.0 release cycle
of LLVM thanks to the target being promoted to non-experimental.
Consequently the WASM linker code in LLD is getting some more broad testing.
In the Zig frontend I've added --no-threads for now, to work around the bug.
Please let me know if there is more information I can provide to help
diagnose and fix this bug in LLD. The repro case I uploaded in the issue
tracker triggers the deadlock about 1 in 6 times for me.
