Does mold now work well with mimalloc 3.x? I notice that mold-2.40.4 changelog explicitly mentioned that they reverted mimalloc to 2.x due to stability issue.

Well, the current version in void's repositories is 2.34.1. I'll pay attention to the more recent versions of mold to see if anything gets updated with their usage of mimalloc.

Also finding that mold bundles its own mimalloc anyway.

Yeah, I'm asking because I intended to update it back then. Now I just settled on whatever version Void ships.

This is not the case though, mold is configured to use system mimalloc in the template.

Either way, this is not a blocker.
