The cargo bump PR doesn't seem to contain the flate2 update.

I suspect the test is somehow depending on zlib C symbols that were previously exported, but are no longer so after the flate2 change

This linker error is exactly the opposite. The linker complains about duplicate definitions, not missing definitions. One of them is from libz-rs-sys, but the cargo update PR doesn't yet have libz-rs-sys in its Cargo.lock.

Ah, this is not for building cargo. This is for a project that depends on cargo as library. You may need to update to flate2 1.1.1 which is the first version using libz-rs-sys 0.5 that avoids symbol conflicts.

Current cargo does have the right version of flate2:

https://github.com/rust-lang/cargo/blob/7918c7eb59614c39f1c4e27e99d557720976bdd7/Cargo.toml#L48

So I suspect this just fixed itself as things got updated?

I can confirm this issue is no longer happening on rust version rustc 1.88.0-nightly (10fa3c449 2025-04-26). I can reverse bisect if needed? Should the issue be closed?

@ChrisDenton

Since this is fixed and we have an explanation for how I think this can just be closed now, thanks!

It can always be re-opened if something else comes up.

Ok I may have jumped the gun on this, seems it still happens on the windows gh-actions runner even though it doesn't on my desktop, I'll try to make a minimal reproducer
