[Bug 1758757] [NEW] Leap2A export warnings on comment/annotation

 

Public bug reported:

On doing an export in PHP 7.0/7.1 I see these warnings

[WAR] 4a (export/leap/lib.php:406) Parameter 1 to
LeapExportElementComment::setup_links() expected to be a reference,
value given, referer: http://testing/export/index.php

[WAR] 4a (export/leap/lib.php:406) Parameter 1 to
LeapExportElementAnnotation::setup_links() expected to be a reference,
value given, referer: http://testing/export/index.php

In the Mahara code it says:
"You must explicitly pass variables by reference when calling call_user_func, ..." 

But in PHP manual itself it says "Note that the parameters for
call_user_func() are not passed by reference."

So there is something not quite right here
