error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.61.0-nightly (52b34550a 2022-03-15) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C embed-bitcode=no -C debuginfo=2

note: some of the compiler flags provided by cargo are hidden

Found previous art: #85350

And I can confirm that the following code causes an ICE (just like the previous ticket did):

impl FnMut(&Context) for 'tcx {
fn print () -> Self :: Output{ }
}

I don't think this is the same issue as the linked issue (that one is malformed).

See #94998 for a smaller repro.

Like jack said about the repro in #94986 (comment): while the ICE is at the same place, it's not the same as this issue, the queries are different. We could close this one as a duplicate of #94998 since it has more information.

I'm going to close this as a duplicate of #94998, since that has a smaller repro, plus a MCVE in comments.
