Bug description: objects destroyed, but not always on callbacks functions
Description:
------------
When I terminate a script by an exit,
before end of execution, ob_start allows to
to invoke a callback function.
>From this callback function, I cannot access to an
object (in source example:$t1) previously initiated in the script.
However, if I save a dummy copy of that object in a new variable (for
instance $t2), then it work as expected.
In the source example, just uncomment the line "$t2=$t1;"
to see what I mean.
I works normally in previous version of php (php 4 and first releases of
5)
I cannot remplace the exit at the end by an ob_flush(), because I'm
including a big script in my real work, which is much more complex than
the example I provide.
Reproduce code:
---------------
<?php
class test{
function nice_string(){
return "hello world, how are you ?";
}
}
$t1 = new test();
// the following commented line makes a difference
//$t2=$t1;
function callbackfunc($output){
global $t1;
$output ="chocolate<br>". $output . "<br>". $t1->nice_string();
return "$output";
}
ob_start('callbackfunc');
echo "what a nice day";
exit(); ?>
Expected result:
----------------
should output:
chocolate
what a nice day
hello world, how are you ?
Actual result:
--------------
output nothing,
blank page,
probably a fatal error without any indication about it.
Uncommenting line $t2=$t1 and it works fine again.
