Round-tripping fails

[finestructure]

It looks like this package is a slightly newer version of https://github.com/marmelroy/Zip and I was hoping it might address a round-tripping issue I reported there.

Unfortunately, this version here (2.2.0) also throws a zipUnfail when trying to unzip the attached file (which was zipped with version 2.1.2).

I thought I'd raise this again here in case it got lost in the other repo. Please feel free to close either as a duplicate if that's not helpful!

As you said in the original issue unzipping the file in Finder works, so I've tried to re-zip it using Finder, and unzipping that with Zip works. I've also tried to re-zip it with Zip 2.2.0, and unzipping that works too. You can see these tests here.

I looked at the C code you pointed to in the original issue and realized that the vendored library is a weird mix of Minizip v1.0 and v1.1 (maybe from some development branch). I updated it to the official v1.1 and then to v1.2, and unfortunately unzipping your original file doesn't work with neither.

Of course it's weird that this library can't unzip a file that other libraries can, so further investigation is needed.
