t/examp.............ok 104/196

t/examp.............ok 105/196Bad symbol for filehandle at blib/lib/DBD/ExampleP.pm line 321.

The offending line is​:

  closedir($sth->{dbd_datahandle});

The only other relevant lines are​:

  $sth->{dbd_datahandle} = "DBD​::ExampleP​::".++$DBD​::ExampleP​::gensym;
  opendir($sth->{dbd_datahandle}, $dir)

I can't see why the test should fail in this way. Smells to me like
a threaded-perl bug or AIX threaded libc bug.

Please confirm that there's no problem with a non-threaded perl.
Please also do a spot of debugging to see what value is in
$sth->{dbd_datahandle} (etc etc) in case that sheds any light on it.

I'd be grateful if someone could test DBI 1.11 with a threaded 5.005_57
on another platform (I don't have time right now).

Tim.
