…space safely Context: - https://blog.rust-lang.org/2024/09/04/cve-2024-43402.html - rust-lang/rust#129962 Note that the Rust test case for this checks that it executes the batch file successfully with the proper mitigation in place, while the Zig test case expects a FileNotFound error. This is because of a PATHEXT optimization that Zig does, and that Rust doesn't do because Rust doesn't do PATHEXT appending (it only appends .exe specifically). See the added comment for more details.
