Compiler error while compiling Winrt

[tensor-programming]

Trying to compile winrt with latest nightly msvc got a internal compiler error.

error: internal compiler error: src\librustc_traits\normalize_erasing_regions.rs:42: could not fully 
normalize `unsafe extern "system" fn(*mut rt::gen::windows::foundation::AsyncActionProgressHandler<TProgress>, *mut 
rt::gen::windows::foundation::IAsyncActionWithProgress<TProgress>, <TProgress as 
rt::RtType>::Abi) -> i32`

note: rustc 1.41.0-nightly (ded5ee001 2019-11-13) running on x86_64-pc-windows-msvc

note: compiler flags: -C debuginfo=2 --crate-type lib

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

query stack during panic:
#0 [normalize_ty_after_erasing_regions] normalizing `ParamEnvAnd { param_env: ParamEnv { caller_bounds: [], reveal: All, def_id: None }, value: unsafe extern "system" fn(*mut rt::gen::windows::foundation::AsyncActionProgressHandler<TProgress>, *mut rt::gen::windows::foundation::IAsyncActionWithProgress<TProgress>, <TProgress as rt::RtType>::Abi) -> i32 }`
#1 [lint_mod] linting module `rt::gen::windows::foundation`
#2 [analysis] running analysis passes on this crate
end of query stack

Saw similar error over with this one: #64908 so figured I would report here and not in the winrt github. Project compiles fine with latest stable on x86-64-pc-windows-msvc.

Can you please provide a backtrace, and if possible, a minimal reproducer? Thanks.

also, I think this is the winrt repo: https://github.com/contextfree/winrt-rust

[pnkfelix]

triage: P-high for now. Removing nomination.

I was able to reproduce it,

Yeah, sorry, haven't been on this machine for a few days. Areredify's backtrace looks right compared to what I saw before.

Heres the full backtrace just in case.

Using cargo-bisect-rustc, I discovered that this was fixed two days later in nightly-2019-11-15. It looks like #66378 was responsible for fixing this.

[pnkfelix]

closing as fixed by PR #66378

[pnkfelix]

@wesleywiser points out this may need a regression test. Reopening, re-prioritizing as P-medium and marking E-needstest.

Triage: I agree it would be good to have a regression test for the ICE. But now, more than three years later, I think we have to accept that no one will write a regression test. Had there been a minimal reproducer, I would have written a regression test myself. But by now it simply is too much effort to figure out how to reproduce and figure out how to minimize the reproducer.

There are 3595 other C-bugs open in this repo (of which 584 are I-ICE and 113 are E-needs-test) that deserves more attention than this issue, and there will always be issues that deserves more attention than this issue. Let's close this.
