Bug description:fatal error with call_user_func and function with by-reference
arguments
Description:
------------
I have a Drupal site. It worked ok until I upgraded php to 5.3.2. It simply
fails, nothing is written to the error log or on the screen.
I tracked down the problem to the following point:
* in some file, there is this call:
return call_user_func($hook_function, $variables, $suggestions);
where $hook_function is _phptemplate_page
* _phptemplate_page function is defined as:
function _phptemplate_page(&$variables, &$suggestions) {
....
}
If I remove the & before variables, the site works. I know the by-reference
variable behavior changed in 5.3.2 from 5.2, but in this case, the actual
parameters are still 2 variables (not constants).
Cheers,
Andrei
Test script:
---------------
<?php
function testfnc1($x) {
echo "testfnc1: $x ";
}
function testfnc2(&$x) {
echo "testfnc2: $x ";
}
$y = 'works';
call_user_func('testfnc1', $y);
call_user_func('testfnc2', $y);
Expected result:
----------------
testfnc1: works testfnc2: works
Actual result:
--------------
testfnc1: works
