I'm seeing this one as well. Host is a standard ubuntu-latest Github Actions container. Not sure if the below information is helpful but its additional to the above posted by HYG-YT.

[HTGAzureX1212]

I have to temporarily degrade the version of my nightly installation to 11-24 to make sure everything is functional (it's a discord bot made with twilight-rs)

[theashguy]

Similarly, I'm attempting to knock my version back a couple of days as well-- yet to succeed but that's mostly me wrestling with my actions configuration.

I have the same on my Raspberry Pi 3 (Debian 10, Linux 4.19.66):

I can reproduce with cargo check on ring.

Assigning P-critical as discussed as part of the Prioritization WG procedure.

[HTGAzureX1212]

I updated to the latest nightly (2020-11-29) and it still fails.

[tesuji]

Wait for next nightly. The current one doesn't contain the fix PR.

[HTGAzureX1212]

Got it! 👍
