Description:
------------
I evaluate broken script with eval function. If display_errors is On i get status 200 in http response, but if is Off i get status 500. It is normal behaviour? error.log is empty.

Reproduce code:
---------------
<?php
ini_set('log_errors', 1);
ini_set('display_errors', 0);
eval('some)broken-code|');

Expected result:
----------------
HTTP/1.x 200 Ok

Actual result:
--------------
HTTP/1.x 500 Internal Server Error

After eval() script continues executing normally and I see expected result on the page.

Quite logically expected: You want to see errors -> errors are shown -> http status is 200. In case there is nothing to output, you get 500.

Where is the logic?

---
<?php
print 123;
ob_flush();
ini_set('display_errors', 0);
eval('aa|bb/cc');

Out: 123 and status 200

---
<?php
print 123;
ini_set('display_errors', 0);
eval('aa|bb/cc');

Out: 123 and status 500

In the first example the headers has already been sent (due to ob_flush()), so PHP can't set the HTTP status code.
