<div dir="ltr">Hi Andrew,<div><br></div><div>I replied to you on the bug report thread.

I would like to bring attention to this bug report:<br>
<a href="https://bugs.llvm.org/show_bug.cgi?id=41508" rel="noreferrer" target="_blank">https://bugs.llvm.org/show_bug.cgi?id=41508</a><br>
<br>
WebAssembly is getting quite some attention in the 8.0.0 release cycle<br>
of LLVM thanks to the target being promoted to non-experimental.<br>
Consequently the WASM linker code in LLD is getting some more broad testing.<br>
<br>
In the Zig frontend I've added --no-threads for now, to work around the bug.<br>
<br>
Please let me know if there is more information I can provide to help<br>
diagnose and fix this bug in LLD. The repro case I uploaded in the issue<br>
tracker triggers the deadlock about 1 in 6 times for me.<br>
<br>
Regards,<br>
Andrew<br>
