@WG-prioritization/alerts issue #75612 has been requested for prioritization.

Procedure

LeSeulArtichaut (Aug 17 2020 at 12:26, on Zulip):

This is a bit of a guess but cloudflare-zlib which is a dependency of oxipng is compiled with AVX enabled on Windows MSVC: https://gitlab.com/kornelski/cloudflare-zlib-sys/-/blob/c70f245e7c9533984aac95a28caed78df39e500a/sys/build.rs#L37. The i5-650 doesn't support AVX which would explain the illegal instruction.

Seems like a noissue? Should we still ping notif groups e.g. Windows group?

Kind of related: support for Win7 has ended. I was curious if there are plans to demote Win7 from Tier1 (like already done for Apple 32bit platforms) or is MS Windows treated as a "single" platform (i.e. 7+8+10)

apiraino (Aug 17 2020 at 16:47, on Zulip):

Maybe label with O-windows-*and keep it in on P-medium while we wait for further analysis?

You should probably ask Pietro Albini or simulacrum

Or we could un-prioritize it until we have some more evidence that this is a problem on rustc's side.

I'll ping windows group, maybe someone can take a look
