"Minimised" to a reproducer involving 3 crates, 2 of which are empty: repo containing repro.

The crates are laid out like so:

root -> my_macro[proc-macro=true] -> dep

root and my_macro are both empty, dep contains the following code:

use std::str::FromStr;

pub fn foo() {
    f64::from_str("");
}

Using that repro I used cargo-bisect to find the offending commit:
searched nightlies: from nightly-2021-03-28 to nightly-2021-06-27
regressed nightly: nightly-2021-05-19
searched commits: from 3e99439 to 4e3e6db
regressed commit: 4e3e6db (#84767)

bisected with cargo-bisect-rustc v0.6.0

Host triple: x86_64-unknown-linux-gnu
Reproduce with:

cargo bisect-rustc --start=2021-03-28 --end=2021-06-27 --script ./test.sh

It's worth adding that this was triggered by syn, so it will probably occur for all crates that depend on a proc macro that depends on syn (i.e. basically everything).

Uhh #84767 is not the PR I would have expected but I guess cc @scottmcm just in case you know why this broke?

Repros on godbolt, so the 2 empty crates don't seem needed: https://rust.godbolt.org/z/KEW4Koz7a

Agreed, @jyn514, I'm also completely surprised that the ? change would break this.

Only thing I could think of would be that somehow it propagated a different type that somehow still compiled, but I've never seen an example of that. And the layout stuff is using LayoutError, which is quite well-behaved -- no weird Froms that could potentially have it do strange things -- and even then it's very sparse on ? usage.

Unless maybe it's another instance of something getting confused by the default parameter on FromResidual somehow? (Not sure how it could be, but rust-lang/rust-analyzer#8692 came to mind.)
