Call-time pass-by-reference has been deprecated

I am getting this also

I have the same error using menu_stp on drupal-6.12-DE.

Did some investigations and as far as I understood this warning is caused by an old (php 4) style of method call using a reference. Found a similar problem somewhere else related to drupal which had been solved by replacing method call
method ( &$var )
by
method ( $var )
So I changed line 27 in menu_stp.module from
_menu_stp_form_alter_menu_edit_item(&$form, &$form_state, $form_id);
to
_menu_stp_form_alter_menu_edit_item($form, $form_state, $form_id);
And luckily it fixed that warning and menu_stp does still work correctly :-)

@Marcel20: I successfully tested you solution. Thx!
Please, can anyone incorporate this in the next release?

Please review this patch before the maintainer commits it

tested and worked ok here.

Should mention that the bug would only be appearing when using php 5.3

I too am getting this error and am hosting the development site on a Windows Server 2008 R2 IIS7 box which logs the error and displays an error 500 when you try to browse the site. I will try the patch also so thanks for that but would love the maintainer to resolve this issue in the next release :-)

Thanks all

After applying the patch I can now browse the site again and the module is enabled however i cant see any options for setting this, I have followed the documentation but still am not seeing from within the menu items edit page a selection for me to add roles :-/ any ideas on this? Im using the latest ver of Drupal 6, I should also say im running the latest version of PHP5.2.

Any help would be great

Thanks

problem resolved simply changed line 27 :-)
