bindeps crashes cargo

[Rustacian]

Problem

adding

redux_helper32 = { path = "../redux_helper32", artifact = "bin", target = "i686-pc-windows-msvc" }

see https://codeberg.org/Rustacian/fdb-mirror/src/branch/master/fdb/Cargo.toml#L33

to a dependency crashes cargo with the following error:

Steps

1. checkout https://github.com/Rustacian/testnew/ (Hello world with config for nightly and bindeps, and one additional dependency)

2. change the dependency

   fdb = { git = "https://codeberg.org/Rustacian/fdb-mirror.git", branch = "master" }

   to

   fdb = { git = "https://codeberg.org/Rustacian/fdb-mirror.git", branch = "main" }

3. observe successful compilation via cargo check (the dependency doesn't use a binary dependency)

4. change back to

   fdb = { git = "https://codeberg.org/Rustacian/fdb-mirror.git", branch = "master" }

   (the branch "master" adds the binary dependency and build.rs)

5. observe crash via cargo check

Possible Solution(s)

No response

Notes

The dependency itself compiles just fine in either version when not compiled as a dependency.
