Yep, this is due to #121644, cc @oli-obk.

Specifically, it's kind of sketchy that the static allocations inherit the codegen flags from their parent statics -- in this case (see the issue @matthiaskrgr linked), we have an static allocation who inherits the #[no_mangle] flag from the parent; however, the allocation doesn't actually have an item name to use for #[no_mangle].

This should also affect other attrs like #[export_name], #[link_name]...

I'm gonna put up a fix PR.
