Should it be avoided? I've never heard anything like that.
And if so, this problem should be marked as a documentation problem.

It seems to me like the user is creating a circular reference, which
should not be done. But, using the latest PHP 5.0/4.3.1 I cannot
replicate the crash.

This bug has something to do with the bug #21600.

I can NOT reproduce this, with either of the scripts..
(It doesn't _crash_ with CLI at least)

Verified with HEAD / PHP_4_3 branch.
The following script causes segfault under php-4.2.3, php-4.3.0,
php-5.0.0dev.
<?php
class foo {
var $fubar = 'fubar';
}
function &foo(){
$GLOBALS['foo'] = &new foo();
return $GLOBALS['foo'];
}
$foo = &foo();
var_dump($foo);
var_dump($foo->fubar);
unset($foo);
$foo = &foo();
var_dump($foo->fubar);
?>

The following script causes my Apache 2.0.43 to crash.
It is repoducable.
PHP 4.3.0 runs as an module.
<?php
class foo {
var $test = 'test';
function bar()
{
echo $this->test;
}
}
function &getFoo()
{
$GLOBALS['foo'] =& new foo();
return $GLOBALS['foo'];
}
$foo =& getFoo();
$foo->bar();
?>
