Compiler error compiling a yew project (wasm32-unknown-unknown target)

[dspadea]

Code

Doesn't seem to be code-related. rm -rf target seems to fix it. The issue didn't show up in nightly, but it's possible that's because nightly did a clean rebuild.

Meta

Issue did not present on nightly (1.59.0-nightly (475b00a 2021-12-24)), BUT this seems to have been some sort of issue with the target/ directory (see above). Nightly did a clean rebuild, which also seemed to fix stable. I.e. I don't know if this proves that the issue is not present in nightly. Inconclusive at best.

[dspadea]

Looks like this might be a duplicate of #92195, perhaps?

[dspadea]

Yeah - found some other issues that look similar enough that I'm guessing this is the known incremental compilation issue being worked on in #91919. Closing this one.
