@WG-prioritization issue #72470 has been requested for prioritization.

Jonas Schievink (May 22 2020 at 22:29, on Zulip):

P-high? This may indicate a miscompilation or at the very least incorrect MIR.

LeSeulArtichaut (May 23 2020 at 18:04, on Zulip):

We should probably ping the LLVM-ICE-breakers?

LeSeulArtichaut (May 23 2020 at 18:05, on Zulip):

Incorrect MIR seems unlikely to me if this bug only happens on Windows

LeSeulArtichaut (May 23 2020 at 18:08, on Zulip):

Also, as the code required for this doesn't seem unlikely to apprear in a "real" projet

LeSeulArtichaut (May 23 2020 at 18:08, on Zulip):

IMO this would have been P-critical if it wasn't Windows-only

Jonas Schievink (May 23 2020 at 18:15, on Zulip):

True. It might be related to the exception handling differences on Windows.

I suppose it can be marked as P-Critical, or would it have to affect everyone ? Windows probably represent a big chunk now ?

LeSeulArtichaut (May 26 2020 at 11:01, on Zulip):

I think it could be marked as P-critical

LeSeulArtichaut (May 26 2020 at 11:01, on Zulip):

IMO miscompilations are always scary

LeSeulArtichaut (May 26 2020 at 11:04, on Zulip):

And if that’s system-dependent, it can be particularly sneaky, and if it ever hits stable it could lead to hard to debug problems

DPC (May 26 2020 at 12:52, on Zulip):

i agree on p-critical and yeah you can ping that group

triagebot (May 26 2020 at 12:56, on Zulip):

Issue #72470's prioritization request has been removed.
