Rust project now fails to link with MSVC: failure during conversion to COFF: file invalid or corrupt

help

Hey y'all :slight_smile:
Back in 2021, a Rust project of mine used to compile and run successfully with nightly-2021-08-14.
Now I wanted to revive this project & compile it but some deps didn't compile with the old nightly, so I upgraded the nightly in the rust-toolchain file to nightly-2024-08-01.
After updating the code (catching up with all the things that changed in the nightly since then, such as box -> Box::new) it compiles fine, but it fails to link, any idea why?
I'm always getting this error:

error: linking with `link.exe` failed: exit code: 1123

I already tried cargo clean several times and updating my MSVC build essentials.
Same error! Any idea why?
I'd appreciate any hint! :slight_smile:

Ah, I figured it out:
Both the top-level crate and a sub-crate are using winres in their build.rs to set the version (and for some reason that didn't cause an error in 2021).
