According to [this mold commit](https://github.com/rui314/mold/commit/5dfa1cf07c03bd57cb3d493b652ef22441bcd71c) this is mostly due to human error (compiler bug that's unfortunately too late to fix without revising psABI), so you may want to mention it somehow to reduce reader confusion. "If not, ... will error" is clearly not the root cause and likely will not satisfy the curiosity of many.
