ERRORLEVEL issue

[Walter Weinmann]

Sorry - unfortunately I am a beginner.

I have a Golang program that runs on an error and ends with panic(). When running on Windows 10 the value of ERRORLEVEL is 0, the same happens when the program is terminated with exit(1).

What am I doing wrong?

Insufficient data. When I run a Go program that does `os.Exit(1)` in a MSYS2 bash shell doing `echo $status` shows the value `1` as expected. Running the same program inside a cmd.exe shell and then doing `echo %ERRORLEVEL%` also reports `1` as expected.

I also wrote a trivial Go program that did nothing more than `panic("WTF")` and it results in an exit status (ERRORLEVEL) of two in both a MSYS2 bash shell and a native cmd.exe shell. So, it is likely you are not testing what you think you are testing.

Same problem with os.Exit(1).

You're building src_go.exe (-o of go build), and running orabench.exe.

I'm not - sec_go is a directory:

This looks as expected ?

Are you saying that if you run this program:

package main

import "os"

func main() {

    os.Exit(1)

}

you see the %ERRORLEVEL% is 0?

Under Linux, calling os.Exit(1) also prints the message "exit status 1".  Does this happen with Windows too?

What version of go are you using?  And which shell are you using to run the script which runs the executable?

[Walter Weinmann]

This simple version is working - it seems to be a more specific issue.  

[Brian Candler]

Are you making an explicit call to panic(), or is it a crash from inside some cgo?  If you are calling panic() is it from somewhere unusual like a signal handler?

I tried a small cgo program to fault and it still exited with code 1 (under macOS anyway) - incidentally the word "panic" doesn't appear in the output.

package main

// typedef int (*intFunc) ();

//

// int

// bridge_int_func()

// {

// return ((intFunc)0)();

// }

import "C"

import "fmt"

func main() {

fmt.Println(int(C.bridge_int_func()))

}

And this one exits with code 2:

package main

// int

// bridge_int_func()

// {

// return *(volatile int *)0;

// }

import "C"

import "fmt"

func main() {

fmt.Println(int(C.bridge_int_func()))

}
