PHP Bug Type: Reproducible crash
Bug description: Segfault if date.timezone is not set and error_log is defined
Description:
------------
When creating a new SoapClient PHP will segfault if the client is
unreachable or returns a 404. This behavior appears to be "fixed" if
date.timezone is defined in php.ini or if error_log is not set
(regardless of whether log_errors is on or off).
Reproduce code:
---------------
try
{
$client = new SoapClient("http://1.2.3.4/wsdl";);
}
catch(Exception $e)
{
echo "\n\nNO SEG FAULT!\n\n";
}
Expected result:
----------------
See 'NO SEG FAULT' printed to screen
Actual result:
--------------
Segmentation fault
