[compiler-errors]

This issue has been regressing and un-regressing for quite some time: #92004

[compiler-errors]

Though most recently this seems to have regressed in #132173 / 7660aed according to bisection.

[compiler-errors]

Given that this only seems to have regressed in a crate that was specifically created to showcase a bug having to do with type overflow in codegen, I'm tempted to say that this is probably an OK regression to swallow.

Related: Is there anything in 7660aed we would like to include in the release notes?

[Mark-Simulacrum]

My sense is there's not anything clear to relnotes there -- at least not related to this issue (that PR is already relnotes for other reasons), especially since it sometimes works and sometimes doesn't. I'm inclined to close as won't fix as @compiler-errors suggested, so going to do that.
