Out of memory with tuple struct initialization, async fn and use

[sgdxbc]

It's very hard to precisely summarize the keywords, feel sorry if I missed a duplicated case when checking previous issues.

Code

In lib.rs

pub struct Foo<F> {
    pub f: F,
}
// these also works: private `f` field, `pub Foo<F>(F);`

impl<F> Foo<F> {
    pub async fn foo() {}
}

In main.rs

use foo::Foo;  // package named `foo`

fn main() {
    Foo(());
}

Run cargo check or cargo build, it looks like compiler allocate memory in infinite loop/recursion and eventually get killed.

Either the following does not trigger...:

• Replace use foo::Foo with mod foo { /* lib.rs content */ }
• Replace Foo(()) with Foo { f: () } with a private f field
• All other variants that passes compilation. (the two cases above reports correct error)

...and after do either of them once, revert the code, rerun

cargo clean and rerun, the issue is back.

This is a duplicate of #119625, which has already been fixed by #119638 on nightly and beta, so I'll close the issue as such. The fix should land on stable 1.77, in 2 weeks.

Thanks for opening an issue!

Thanks!

I so love the language when every annoying thing of it has a deadline to disappear :)
