`rust_doc_test` failing with "Failed to load argument file"

[UebelAndre]

I'm not entirely sure when this started occurring but I'm seeing the following error in some rust_doc_test targets

==================== Test output for //:rustdoc_test:
error: Failed to load argument file: IO Error: rustdoc_test.rustdoc_test.sh-0.params: No such file or directory (os error 2)

================================================================================

Through some bisecting I found the change in behavior to happen between bbccf77 and c435cf4 but that delta doesn't make much sense to me since neither of these commits look like they'd impact this behavior. Perhaps the error message is not deterministic. This also no longer seems to happen for hosts other than windows. More info is needed.

In case it helps, we're also seeing this error, on both Linux and MacOS.

Could you share what commit of rules_rust you started seeing this on?

I also hit this error in #1252. Since the //crates_universe:rustdoc_test target worked before that change on MacOS, it can hopefully reveal the root cause of this issue.

We're on ea22478f6dac4604b4ef38fb8e713cd1c0880084. This is the first time we're trying to use this rule in our repo, so we don't have "good" commits where this is working.

I'm also noticing the issue on the project I'm porting to Bazel

error: Failed to load argument file: IO Error: src/many/many_doc_test.rustdoc_test.sh-0.params: No such file or directory (os error 2)

I'm using rules_rust git e83d5f3 on Linux.
