I've verified that by reverting e2a591dca, I can get past this error.

[gsjaardema]

I am working with the lib::fmt developers to see if we can get a fix for the intel compiler. Hopefully something today, but maybe better to just revert...

[jrood-nrel]

Can we get this reverted?

[jhux2]

@jrood-nrel PR #10179 is in flight to fix this.

[jrood-nrel]

I think it would be best to revert this so our GPU tests can run again.

[jhux2]

@jrood-nrel I think that's the plan if @gsjaardema can't resolve this today.

[jhux2]

@jrood-nrel #10179 should fix this issue. (Thank you, @gsjaardema!) I verified that my build on Summit finishes successfully with the PR, and fails without it. Once you've verified that your builds are clean, could you please close?

[jrood-nrel]

Sure. Thanks!

[jrood-nrel]

This looks fixed, but I can't close it.
