Summary: eval'ed Code throws HTTP 500 error when
display_errors is off
Status: Bogus
Type: Bug
Package: Output Control
Operating System: Linux
PHP Version: 5.2.6

New Comment:
I've ran into the same problem on 5.2.9. Because of an error in the
eval'd code(and the subsequent 500-Internal error generated), the
headers i was sending from my app would get misinterpreted by the
browser and would display a "File Not Found"...
I tracked this to a combination of "display_errors off" and the eval
function.

Why bogus?
This is by no means a consequent error-reporting.

"Changed error handler to send HTTP 500 instead of blank page on PHP
errors. "
1. I've never seen a blank page in PHP4, when i'm doing @eval !
2. Why does it work with display_errors on?
3. Why does it work, when i'm doing an "echo" BEFORE the @eval?

That's expected behavior.
In PHP 5.2.4 NEWS:
"Changed error handler to send HTTP 500 instead of blank page on PHP
errors. "
And in the manual page for eval(): http://docs.php.net/eval
"If there is a parse error in the evaluated code, eval() returns FALSE
and execution of the following code continues normally. It is not
possible to catch a parse error in eval() using set_error_handler()."

Sorry ..
the code example goes in the wrong direction
I've narrowed the actual issue. It has to do with evaled code.
The @eval-Function is not catched properly.
<?php
error_reporting(E_ALL & ~E_NOTICE);
class Test {
function func1() { // HTTP 500
ini_set('display_errors', 'off');
@eval('completely wrong');
echo 'boo'; exit();
}
function func2() { //HTTP 200
ini_set('display_errors', 'on');
@eval('completely wrong');
echo 'boo'; exit();
}
function func3() { // HTTP 200 and HTTP 500 with output buffering
ini_set('display_errors', 'off');
echo 'noerror';
@eval('completely wrong');
echo 'boo'; exit();
}
}
Test::func1();
//Test::func2();
//Test::func3();
?>

You have a parse error there:
PHP Parse error: syntax error, unexpected T_STRING, expecting
T_VARIABLE in /home/jani/t.php on line 7
And I don't get any E_STRICT notices with fixed version of this code
either..
