ICE on 1.51.0 stable: 'LocalTableInContext: key not found'

[trtsl]

I get the following ICE with rustc 1.51.0 stable (but not on nightly). The ICE can currently be reproduced on the playground.

Code

fn foo<F>(_: &mut F)
where
    F: FnMut(),
{
}

fn main() {
    let f = || {};
    foo(&mut f);
}

[trtsl]

Even simpler: playground.

fn main() {
    let f = || {};
    drop(&mut f);
}

[fanninpm]

This ICE also does not happen in the 1.52 beta.
