@WG-prioritization/alerts issue #80772 has been requested for prioritization.

Procedure

apiraino (Jan 07 2021 at 13:59, on Zulip):

According to godbolt the ICE starts with 1.41 https://godbolt.org/z/cdMx8P
Up to 1.40 code compiles with some warnings

apiraino (Jan 07 2021 at 14:01, on Zulip):

not sure though if it's a bad sign or just something else

Ryan Levick (Jan 07 2021 at 14:06, on Zulip):

Seems hard to reproduce. Making almost any change to the example makes it not ICE

Yuki Okushi (Jan 08 2021 at 06:57, on Zulip):

looks like #74599 has the same cause (or they fail on the same place at least) but this doesn't requires-nightly

Yuki Okushi (Jan 08 2021 at 06:58, on Zulip):

P-medium or P-high?

apiraino (Jan 08 2021 at 12:03, on Zulip):

I can mention for a bisection, would that help? If we find the culprit maybe we understand how far in the past this goes and understand if it's critical

Bisecting it now: https://github.com/bjorn3/cargo-bisect-rustc-bot/issues/1#issuecomment-757030346

apiraino (Jan 13 2021 at 10:39, on Zulip):

I feel this can be a P-medium.

triagebot (Jan 14 2021 at 11:50, on Zulip):

Issue #80772's prioritization request has been removed.
