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 1.62.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib

query stack during panic:
#0 [try_normalize_generic_arg_after_erasing_regions] normalizing `impl core::future::future::Future<Output = ()>`
#1 [mir_drops_elaborated_and_const_checked] elaborating drops for `test::{closure#0}`
#2 [optimized_mir] optimizing MIR for `test::{closure#0}`
end of query stack

Typo in issue number: It should be #95034. cc #96783.

FWIW, not all the repros of the issue passes through this debug_assert. Indeed, only the original one does. Other repros fails on other related non-debug assertions.

@matthiaskrgr Is this ticket necessary? given that this is known-bug test and the issue for it is open.

Whoops.

Yeah, I'm going to close this as this debug assertion failing is a symptom of the underlying issue that this test is tracking. @matthiaskrgr, let me know if that's not fine.
