Beware that there is a critical bug in that release if you use

-Wl,-zcommon-page-size=0x200000 -Wl,-zmax-page-size=0x200000

or similar - I already filed a bug report and it has been confirmed.

Mold is an absolute blast to use, you can add it to your rust projects pretty easily, and it has worked with almost every project I've used it with (apart from a project which called libpostal, which is a C library).

Looks like that was fixed in https://github.com/rui314/mold/commi...3c6ee38e6dc11c, which preceded the tagging of 1.5.0.

That was the first try. Unfortunately that did not fix it. See my issue about the details, this was reproduced independantly of me with the new version, too.

is there any disadvantage to using mold? (I don't mean when something breaks with mold)
like, could the binaries be slower because mold does not optimize as much as LD or does it differently? (link time optimizations and stuff) or is the result the same just the process of doing it is faster?

Unfortunately, I tend to leave it off because the methods I tried broke things like `cargo miri` and/or cross-compiling and, when you try to make it conditional, it tends to be accomplished by modifying things that cause Cargo to invalidate its incremental build caches too readily.
