I compile PHP 5.3.8 from src with: './configure'
'--with-apxs=/usr/local/sbin/apxs' '--enable-debug' '--enable-zend-multibyte'
I tried to get coredump, but i can find it anywhere.
When i start apache (with -X) i see:
php53test# apachectl13 start
Processing config directory: /usr/local/apache/conf/includes13/*.conf
Processing config file: /usr/local/apache/conf/includes13/13.s16.ihead.ru.conf
After that i make two requests to the Apache.
1) Processed and is see text of syntax error (command line ok)
2) I see blank page (command line print "Bus error")
After that i see text in the command line:
Bus error
/usr/local/sbin/apachectl13 start: httpd could not be started
In the logs such records:
[Sat Sep 3 14:19:40 2011] [warn] pid file /usr/local/apache/logs13/httpd.pid

Description:
------------
--enable-zend-multibyte in "configure" script (Zend Multibyte Support =
Enabled) cause Apache's child processes outputs any result, but exit on signal
10 when in PHP-script there is syntax error and when MaxRequestPerChild != 1.
Tested on Apache 1.3 and Apache 2.2 building PHP from FreeBSD ports or from
source directly.
Test script:
---------------
<?
echo '123';
func($item;
?>
Expected result:
----------------
Work correctly on any next request
Actual result:
--------------
Apache's child proccess outputs any result (text of syntax error) and exit with
signal 10. It cause fails at the next request (Apache server close connection
without any result), when request is scheduled to the killed child.
