Windows installation of Swift 5.9 is suddenly failing without much diagnostic info.

[dabrahams]

• I have gone through the action README, documentation and wiki.
• I don't see my issue listed in existing issues.

Describe the bug
Getting installed Swift version swift-5.9.2-RELEASE
C:\hostedtoolcache\windows\swift-5.9.2-RELEASE-windows10\5.9.2\x86_64\Developer\Toolchains\unknown-Asserts-development.xctoolchain\usr\bin\swift.exe --version
Error: The process 'C:\hostedtoolcache\windows\swift-5.9.2-RELEASE-windows10\5.9.2\x86_64\Developer\Toolchains\unknown-Asserts-development.xctoolchain\usr\bin\swift.exe' failed with exit code 3221225781

To Reproduce
using the windows-latest runner,

    - name: 'Set up swift'
      uses: SwiftyLab/setup-swift@latest
      with:
        swift-version: 5.9

Logs
Please see this link.

This is a re-run of a CI run that was successful a few weeks ago, so it should have succeded..

Screenshots
If applicable, add screenshots to help explain your problem.

Runner (please complete the following information):

• Name: windows-latest
• OS: windows-2022
• Version 20240421.1.0

Everything google tells me about exit code 3221225781 seems to indicate there is a missing Microsoft VC++ Redistributable.

OK, this is really weird. I have exactly the same action succeeding on windows-latest in a different project. When I diff the logs for the setup swift step in these two projects, they are largely identical, but one thing stands out: when this command executes:

[command]C:\Windows\system32\cmd.exe /k "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\Tools\VsDevCmd.bat" -arch=x64 && set && exit

It dumps the environment, and the Path variables are different. In the case where the action works, there is one additional entry in the Path that is not present where the action fails:

C:\hostedtoolcache\windows\swift-5.9.2-RELEASE-windows10\5.9.2\x86_64\Swift\runtime-development\usr\bin

The complete diff of the two logs, in case I've overlooked something else that's important, is here:

Sure enough, when I turn on logging, in the failing case I see:

Note: I have deleted the cache and re-run the command, which has no effect on the result.

Oh, this is creepy: when I enabled debug logging in the project that was working, it started failing in the same way.

[dabrahams]

The runner images used by passing and failing cases appear to be identical.

Using Swift 5.10 appears to work, but it leaves Path set such that when swiftc is used to link, it finds /usr/bin/link rather than the link.exe that comes from the MS tools:

/usr/bin/link: extra operand '/OUT:lib\\ArgumentParserToolInfo.lib'

Try '/usr/bin/link --help' for more information.

My current workaround is to conditionally use compnerd/swift-setup for Windows, which requires a preceding setup-vsdevenv (or it will find the wrong linker as above). I am really sad that there isn't one clean action that works everywhere.

Nope, this is still broken. Please reopen this issue.
