Hi monks, I have a MyOwnTable class which inherits from Data::Table and several derived classes (for example, A) which inherit from MyOwnTable. When I create an instance of A, perform some operations on A (which are not necessary, btw), and then exit the script, I get the following warnings 
Use of uninitialized value in require at //ms/dist/perl5/PROJ/AutoLoad
+er/5.68/lib/perl5/AutoLoader.pm line 27 during global destruction.

When I look at line 27 in AutoLoader.pm, I find the following 
AUTOLOAD {
     my $sub = $AUTOLOAD;
    my $filename = AutoLoader::find_filename( $sub );

    my $save = $@;
    local $!; # Do not munge the value. 
    eval { local $SIG{__DIE__}; require $filename }; ## line 27!!!!
    if ($@) {
        if (substr($sub,-9) eq '::DESTROY') {
            no strict 'refs';
            *$sub = sub {};
            $@ = undef;
        } elsif ($@ =~ /^Can't locate/) {
            # The load might just have failed because the filename was
+ too
            # long for some old SVR3 systems which treat long names as
+ errors.
            # If we can successfully truncate a long name then it's wo
+rth a go.
            # There is a slight risk that we could pick up the wrong f
+ile here
            # but autosplit should have warned about that when splitti
+ng.
            if ($filename =~ s/(\w{12,})\.al$/substr($1,0,11).".al"/e)
+{
                eval { local $SIG{__DIE__}; require $filename };
            }
        }
        if ($@){
            $@ =~ s/ at .*\n//;
            my $error = $@;
            require Carp;
            Carp::croak($error);
        }
    }
    $@ = $save;
    goto &$sub;
}

when I put a breakpoint in AutoLoader::AUTOLOAD, the missing function seems to be A::DESTROY. So, I tried putting a DESTROY method in A (not sure what code should go in there). This resulted in AutoLoader::AUTOLOAD not getting called, but the error/warning still showing up (this is puzzling). Can anyone help me ? thanks, Michael
