 bug report: Archive::Tar-0.21 in perl 5.6.0 on i686 RHL6.1

I have discovered a very unusual bug in Archive-Tar-0.21 and
Compress-Zlib-1.08 under perl 5.6.0.  The test script below doesn't

not printed, or neither is printed.  Something about including *both*
the file list print statement and the hello print statement causes the
crash on the call to get_content.  I have only tried this on one
system (a RHL6.1 i686; full version info below) and have never seen
another bug like it.

Here's the command that produces the crash and the error:

Quote:
> testperl test.tar

test
hello
Can't call method "gzseek" on an undefined value at /usr/local/lib/perl5/site_perl/5.6.0//Archive/Tar.pm line 785.

Here's the 'testperl' script:
#!/usr/local/bin/perl -w
use Archive::Tar;
my $tarfile = shift;
my $tar = Archive::Tar->new($tarfile) or die "can't read tar file: $!";


  print "$_\n";   #comment out this line and the get_content call won't crash!

Quote:
}

print "hello \n"; #comment out this line and the get_content call won't crash!
my $content = $tar->get_content("test");
print "$content\n";

Here's a history to make the test.tar file:
    87  15:05   echo 'world' > test
    88  15:05   tar cvf test.tar test

Very bizarre!
