Does LWP::UserAgent->request() somehow break system()?

[Jeremy Elson]

Hi,

I am experiencing a very strange problem with the latest version of
LWP (perl 5.6.0, LWP 5.48 fresh off CPAN, running under QNX Neutrino).
Calls to system() seem to break after a call to
LWP::UserAgent->request().

For example, in a code fragment such as the following, the "THIS IS A
TEST" messages 0, 1, and 2 succeed, but 3 and all subsequent calls to
system() do not work:

    my($data) = "Test Data";
    my($url) = "http://some.url/receiver.pl";

    system "echo THIS IS A TEST - 0";

    # Construct the HTTP post request
    my $request = new HTTP::Request POST => $post_url;
    $request->content_type('application/octet-stream');
    $request->content($data);

    system "echo THIS IS A TEST - 1";

    # Post it
    my $ua = new LWP::UserAgent;

    system "echo THIS IS A TEST - 2";

    my $result = $ua->request($request);
    
    system "echo THIS IS A TEST - 3";


I've been banging my head against the wall on this for a couple of
hours.  Any idea what might be causing this?

Jeremy
