[go-nuts] panic does not write to duped file

Hello Folks,

I have program that programmatically changes stderr to write to a file, if
an error log has been defined in it's config file. That works fine, however
I have found that a runtime panic does not write to the error file. The
code I used follows:

errorLog, err := os.OpenFile(fqFile, os.O_WRONLY|os.O_APPEND|os.O_CREATE,
0666)
exitOnError(err)

os.Stderr.Close()

// I have tried the following variations:

// os.Stderr = errorLog

// and...
stderrFD := int(errorLog.Fd())
err = syscall.Dup2(2, stderrFD)
exitOnError(err)


I have reviewed the documentation and tried searching on "golang panic" and
other terms, but have not found any useful information. Any help would be
much appreciated.

Thanks,

Daryl
