@WG-prioritization/alerts issue #76984 has been requested for prioritization.

Procedure

Hameer Abbasi (Sep 20 2020 at 19:28, on Zulip):

How frequently used is this toolchain? If someone else can repro it and the toolchain is fairly often used then this should be critical.

If the bug report is right, I don’t see how CI didn’t catch this.

Hameer Abbasi (Sep 20 2020 at 19:29, on Zulip):

I assume we only test MSVC on Windows.

Joshua Nelson (Sep 20 2020 at 19:32, on Zulip):

I'm pretty sure we test GNU but you could ask in #t-infra

Joshua Nelson (Sep 20 2020 at 19:32, on Zulip):

I suspect we have some dependency installed in the CI builder that doesn't come with mingw by default

Fred Østrem (Sep 20 2020 at 19:32, on Zulip):

The x86_64-pc-windows-gnu target (with MinGW) is listed as tier 1 ("guaranteed to work"), so it should have passed tests

Hameer Abbasi (Sep 20 2020 at 19:34, on Zulip):

I‘m assuming we have a test for an empty main. 😅

Hameer Abbasi (Sep 20 2020 at 19:37, on Zulip):

It’s sleeping time here, so I’ll run a bisection tomorrow Morning (if someone hasn’t done it by then).

Fred Østrem (Sep 20 2020 at 20:26, on Zulip):

I tried reproducing the issue, but wasn't able to. Haven't used Rust in Windows previously (only inside WSL), so it was a clean install of MinGW-w64. Tried on stable, latest nightly (2020-09-19) and the nightly mentioned in the issue that was supposed to be broken (2020-09-09). All three build fine for me, so I'm not sure exactly where the issue is.

Fred Østrem (Sep 20 2020 at 20:40, on Zulip):

Hmm, tried a bit more and I was able to reproduce by replacing the gcc installation I had (Mingw-w64 install from Msys2) with the one mentioned in the issue (TDM-GCC). So it might be an issue with that specific compiler?

Jonas Schievink (Sep 20 2020 at 20:55, on Zulip):

Yeah, sounds like we can close this then. We only support what we ship/test with/document, so not TDM-GCC.

Santiago Pastorino (Sep 23 2020 at 16:00, on Zulip):

do someone want to proceed and close this one then?, don't have a lot of context myself

apiraino (Sep 23 2020 at 18:00, on Zulip):

Don't have enough context, too, but it looks like is can be safely closed. I'll close it myself if there are no further comments to investigate the issue (which of course can be always be re-opened)

Santiago Pastorino (Sep 30 2020 at 21:53, on Zulip):

should we remove I-prioritize from this issue?

Joshua Nelson (Oct 01 2020 at 00:29, on Zulip):

I think we should give it P-low - it looks like there's a bug here but for an unsupported toolchain

Hameer Abbasi (Oct 01 2020 at 04:20, on Zulip):

I'd be for close, because... Well... We don't want too many "unsupported" issues littering the tracker.

Hameer Abbasi (Oct 01 2020 at 04:21, on Zulip):

@Joshua Nelson Does that sound good?

lzutao (Oct 01 2020 at 04:48, on Zulip):

unless people show up for helping fixing the issue, closing makes sense to me.

triagebot (Oct 01 2020 at 05:24, on Zulip):

Issue #76984's prioritization request has been removed.
