@compiler-errors compiler-errors commented Feb 20, 2025

Fixes #137288.

See the comment I left on the probe. I'm not totally sure why this depends on both an unconstrained type parameter in the impl and a type error for the self type, but I think the fix is at least theoretically well motivated.

Use a probe to avoid registering stray region obligations when re-checking drops in MIR typeck

Fixes rust-lang#137288.

See the comment I left on the probe. I'm not totally sure why this depends on *both* an unconstrained type parameter in the impl and a type error for the self type, but I think the fix is at least theoretically well motivated.
