os/exec: Doesn't properly report exit code of a "is not recognized as an internal or external command" command

[gopherbot]

by Kusold:

What does 'go version' print? 1.2.1 windows/amd64

On Windows, run the attached .go file. The exitcode that is reported is a "1".
However when you run the attached .bat file, you will see that Windows reports this
error as a 9009.


What happened?
The exitcode that Go is reporting is "1".
The exitcode that Windows is reporting is 9009.

What should have happened instead?
Go should report 9009

Comment 2:

Your two programs (.go and .bat) are not the same. I've changed your .bat file to match
what .go program does, and now it (.bat program) reports the same error:
C:\a>type testWindowsExitCode.bat
cmd /C foo
echo %ERRORLEVEL%
C:\a>testWindowsExitCode.bat
C:\a>cmd /C foo
'foo' is not recognized as an internal or external command,
operable program or batch file.
C:\a>echo 1
1

Status changed to Invalid.
