Compiler error when using nursery

[trentG92]

Attached is the compiler error that gets thrown when calling RUST_BACKTRACE=1 cargo clippy -- -W clippy::nursery. This seems to only occur here when using clippy::nursery.

compiler: rustc 1.70.0 (90c541806 2023-05-31)

error: internal compiler error: no errors encountered even though `delay_span_bug` issued

error: internal compiler error: used a `TypeErrCtxt` without failing compilation

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-clippy/issues/new

note: Clippy version: clippy 0.1.70 (90c5418 2023-05-31)

query stack during panic:
end of query stack

[y21]

Does this still happen in a more recent nightly build? rustc 1.70.0 (90c541806 2023-05-31) is quite old and very similar ICEs have been fixed since then (#10645 for example has the same backtrace and is already fixed)

[J-ZhengLi]

looks like the problem originated from this line in future_not_send:

rust-clippy/clippy_lints/src/future_not_send.rs

Lines 94 to 95 in 87f8a5b

	infcx
	.err_ctxt()

but I can't reproduce the problem without some code snippet to start with~

@trentG92 Hi, sorry for the ping but could you try with rust 1.71 or later? (The issue y21 mentioned was fixed after 1.71) So, maybe it has already been fixed.

[Jarcho]

Closing as this is likely the same as #10645 which is already fixed. @trentG92 if this still occurs on the current version just leave a comment and we can reopen this.
