Could you add a regression test like #97328? |

Thanks! I'm going to defer to @compiler-errors for the rest of the reviews. |

Hi @LYF1999, I don't know if this is the right fix. Can you give me some time to do investigation? Thanks. |
|
@compiler-errors Sure, take your time. |

@compiler-errors Thanks! |

don't do `Sized` and other return type checks on RPIT's real type Fixes an ICE where we're doing `Sized` check against the RPIT's real type, instead of against the opaque type. This differs from what we're doing in MIR typeck, which causes ICE rust-lang#97226. This regressed in rust-lang#96516 -- this adjusts that fix to be a bit more conservative. That PR was backported and thus the ICE is also present in stable. Not sure if it's worth to beta and/or stable backport, probably not the latter but I could believe the former. r? `@oli-obk` cc: another attempt to fix this ICE rust-lang#97413. I believe this PR addresses the root cause.
