Mismatched types causes ICE in compiler/rustc_hir_typeck/src/fn_ctxt/checks.rs:2591:13 #144984
Description
Code
Discovered by @wmstack when compiling PR #144935 in CI at commit ff668ec. CI logs link.
The func(&tmp) should have been func(tmp.as_ref()). So, the code shouldn't compile, but shouldn't ICE either.
