[ID 20000125.010] Globref locally assigned to glob in method doesn't work

[mjd@plover.com]

This is a bug report for perl from mjd@plover.com,
generated with the help of perlbug 1.26 running under perl 5.00503.


-----------------------------------------------------------------
[Please enter your report here]

I have a trivial module, Mod.pm.  It has two methods.  The constructor
accepts a globref and creates an object that contains the globref as
member data.  The other tries to read a line of data from the
filehandle associated with the globref.  However, the data is not
forthcoming. 


Here is file '/tmp/t1', my test script:

================================================================
use Mod;
open TF, "< /tmp/t1" or die;
my $o = Mod->new(FH => \*TF);
my $data = $o->readit;
print $data;

================================================================


Here is file '/tmp/Mod.pm', the module:

================================================================

package Mod;

sub new {
  my ($pkg, $fh) = @_;
  my $self = {FH => $fh};
  bless $self => $pkg;
}

sub readit {
  my $self = shift;
  local *FH = $self->{FH};
  my $str = <FH>;
  return $str;
}

1;

================================================================

When I run the program /tmp/t1, I expect it to print out
its own first line:

	use Mod;

instead, it prints nothing.
