I should have mentioned that I tried IO::Scalar. The following code causes a page fault in perl56.dll. 

use IO::Scalar;

print "Trying ioscalar...\n";
my $io = ioscalar();
print "Finished with ioscalar.\n";
print $io;

print "Testing STDERR...\n";
print STDERR "(STDERR) can you hear me now?\n";

sub ioscalar {
  my $data;
  *oldfh = select STDERR; # save STDERR
  print "STDERR saved.\n";
  my $SH = new IO::Scalar \$data;
  print "\$SH created.\n";
  open(STDERR, '>', $SH) || die "Can't redirect STDERR to the IO::Scal
+ar, $!";
  print "STDERR redirected to \$SH\n";
  select(STDERR); $| = 1;
  print STDERR "ioscalar says 'hi'\n";
  close(STDERR);
  open(STDERR, ">&oldfh"); # restore STDERR
  select(STDOUT);
  return $data;
}

__DATA__
Trying ioscalar...
STDERR saved.
$SH created.
