Hello,

I want to capture the output of a command. I use IO::CaptureOutput. In simple programs, it works fine. As soon as I move it into a program running under CGI.pm 3.42, it does not work. See below for details. 

use IO::CaptureOutput qw(qxy);
($output) = qxy(qw(/usr/local/bin/blaaaargh));
say "<blaaaargh failed: $output>";

Expected result: 

<blaaaargh failed: /tmp/blaaaargh: Permission denied
>

in the browser

Actual result: 

<blaaaargh failed: >

in the browser 
[Wed Nov 05 16:07:39 2008] [error] [client 127.0.0.1] /tmp/blaaaargh: 
+Permission denied

in the error_log

I also ran the CGI program from the command line with use CGI qw(:debug) and could verify that the error message comes first on STDERR, then comes the normal output on STDOUT (again, with the error message missing).

What do I do?
