As pointed out by Eric Wong (thanks), the initial close needs to go:
die() would again write nowhere if we close STDERR beforehand.

Perhaps we should also do the following:

--- a/perl/Git.pm
+++ b/perl/Git.pm

@@ -1489,9 +1489,6 @@ sub _command_common_pipe {
 		if (not defined $pid) {
 			throw Error::Simple("open failed: $!");

-				close STDERR;
-			}
 			if ($opts{STDERR}) {
 				open (STDERR, '>&', $opts{STDERR})

				or die "dup failed: $!";

Indeed.  Thanks for pointing that out.

  I'm sorry, I don't follow. Doesn't this just break the STDERR option
altogether as we will try to dup2() over an already open file
descriptor? We do need to close STDERR if we are going to reopen it,
I think.

  Kind regards,
