Since 2023-04-21 (fec9adcdb), nightly fails to compile geo crate in release mode with [E0275]

[tim3z]

I tried the following:

git clone https://github.com/georust/geo.git && cd geo # main or latest release (tag 0.24.1) both have the issue
rustup run nightly-2023-04-22 cargo build --release

I expected to see this happen: It compiles 🤷‍♂️

Instead, I get the following compiler error:

error[E0275]: overflow evaluating the requirement `[closure@geo/src/algorithm/map_coords.rs:855:69: 855:72]: Fn<(geo_types::Coord<T>,)>`
  |
  = help: consider increasing the recursion limit by adding a `#![recursion_limit = "256"]` attribute to your crate (`geo`)
  = note: required for `&[closure@geo/src/algorithm/map_coords.rs:855:69: 855:72]` to implement `Fn<(geo_types::Coord<T>,)>`

For more information about this error, try `rustc --explain E0275`.
error: could not compile `geo` (lib) due to previous error

Adding the suggested #![recursion_limit = "256"] does not help. I checked up to #![recursion_limit = "1024"] but it started getting veeeery slow.

However, all of the following work just fine:

rustup run nightly-2023-04-22 cargo build # no --release
rustup run nightly-2023-04-21 cargo build # one day before
rustup run stable cargo build --release # stable 1.69

It looks like the code in question: https://github.com/georust/geo/blob/c31ac453ac6565cf17f9d983ab16a892b8b1e451/geo/src/algorithm/map_coords.rs#L851 is trivially recursive?

I think this has the same root cause as #110475 if nothing else it looks incredibly similar.

[tim3z]

Yeah, seems pretty much like exactly that.

I'm going to close this as a duplicate of #110475.
