Upgrading to critical, as it is a crash and clear breakage of
functionality.

Here is one thing that has been more clear in the other, duplicate and
now closed - bug entry (#46338). The first code sample with object
methods does not only miss out on the second error handler, it also
segfaults *on shutdown* of the PHP process:
---SNIP-
Starting program: /usr/bin/php5 segfault2.php

Description:
Stacking 2 error handlers is broken. With object methods only the first
error handler is invoked, with functions I even get a PHP crash.
Reproduce code:
---
-- Object methods ---
?php
class ErrorHandling
{
public function errorHandler1( $errno, $errstr )
{
echo Caught on first level: '$errstr'\n;
return true;
}
public function errorHandler2( $errno, $errstr )
{
echo Caught on second level: '$errstr'\n;
return true;
}
}
$err = new ErrorHandling();
set_error_handler( array( $err, 'errorHandler1' ) );
set_error_handler( array( $err, 'errorHandler2' ) );
trigger_error( 'Foo', E_USER_WARNING );
?
-- Functions ---
?php
function errorHandler1( $errno, $errstr )
{
echo Caught on first level: '$errstr'\n;
return true;
}
function errorHandler2( $errno, $errstr )
{
echo Caught on second level: '$errstr'\n;
return true;
}
set_error_handler( 'errorHandler1' );
set_error_handler( 'errorHandler2' );
trigger_error( 'Foo', E_USER_WARNING );
?
Expected result:
-- Object methods ---
Caught on second level: 'Foo'
-- Functions ---
Caught on second level: 'Foo'
Actual result:
--
-- Object methods ---
Caught on first level: 'Foo'
-- Functions ---
Caught on first level: 'Foo'
