wrong md5 result for export

On my system I do get a different RREF when running conan export compared to what our CI does.

CI:

$ conan export conan/recipes/zeromq/all/ 4.3.3-win@
Exporting package recipe
zeromq/4.3.3-win exports: File 'conandata.yml' found. Exporting it...
zeromq/4.3.3-win exports: Copied 1 '.yml' file: conandata.yml
zeromq/4.3.3-win exports_sources: Copied 1 '.txt' file: CMakeLists.txt
zeromq/4.3.3-win: The stored package has not changed
zeromq/4.3.3-win: Using the exported files summary hash as the recipe revision: e025e41363dcd4b490418d06224d5533
zeromq/4.3.3-win: Exported revision: e025e41363dcd4b490418d06224d5533

My machine:

$ conan export conan/recipes/zeromq/all/ 4.3.3-win@
Exporting package recipe
zeromq/4.3.3-win exports: File 'conandata.yml' found. Exporting it...
zeromq/4.3.3-win exports: Copied 1 '.yml' file: conandata.yml
zeromq/4.3.3-win exports_sources: Copied 1 '.txt' file: CMakeLists.txt
zeromq/4.3.3-win: The stored package has not changed
zeromq/4.3.3-win: Using the exported files summary hash as the recipe revision: 72778c1dd07e4d8976aa4cd2aee084e3
zeromq/4.3.3-win: Exported revision: 72778c1dd07e4d8976aa4cd2aee084e3

On CI, the conanmanifest.txt looks like this:

1613651222
conandata.yml: 0d768f680a5e682de512422da2c25303
conanfile.py: 7b6de2daa28836def00c57e07515612d
export_source/CMakeLists.txt: a7384d1eb57761e50fe52fd0d6bb97a8

on my machine:

1613641780
conandata.yml: 7754e2e98f18114fb783b276051d70fe
conanfile.py: 7b6de2daa28836def00c57e07515612d
export_source/CMakeLists.txt: a7384d1eb57761e50fe52fd0d6bb97a8

So it looks like the md5 for conandata.yml is calculated wrong on my machine. Doing it manually gives the CI version of the md5: md5sum conan/recipes/zeromq/all/conandata.yml

0d768f680a5e682de512422da2c25303  conan/recipes/zeromq/all/conandata.yml

maybe related stuff?

different algorithm may be used: https://github.com/conan-io/conan/blob/e04135f92dcc9d339a728324b8a588c8ae167bb4/conans/util/files.py#L144 https://github.com/conan-io/conan/blob/e04135f92dcc9d339a728324b8a588c8ae167bb4/conans/util/files.py#L162

Both are on the same OS? Something in my head just screams EOL convention. We set all conanfile.py / conandata.yml to Linux EOL conventions, even on Windows, because they caused the creation of different packages. But might be something different in your case.
