Not a defect when
The bounds are cfg- or target-dependent constants that only collide in this configuration, so the condition is satisfiable on other builds.
What it reads
Clippy, with the compiler behind it. The only pass that compiles.
Tier
Serious: worth interrupting other work for.
The tier bounds how severe a rule may be; its category bounds the tier.Diff scope
The changed line itself.

Turn it off, or make it blocking, without touching the code it flags:
rust-doctor --rule clippy::impossible_comparisons=off .
rust-doctor --rule clippy::impossible_comparisons=error .
