Bug description:Crashes on using variable equal to conditional shortcut
Description:
------------
I am using Apache 2.4 with PHP 5.4 on Windows 7 32bit. When executing the
code shown, from within a private class method, the server crashes. PHP is
compiled as a DSO. If the code is changed to utilize long form conditional
processing the execution works.
If I use the command line to execute the script, the class loaded by
require does not get called.
// my index.php
require("C:/Infinity/application/shared/classes/a.php");
$x = new a();
// my a.php
class a { __constructor(){ $this->import_variables($_POST); }}
further code in test script.
Test script:
---------------
# retrieve caller name
$calledby = debug_backtrace(); print_r($calledby);
// does not work
$caller = (strlen($calledby[1]['class'])) ? $calledby[1]['class'] :
$calledby[0]['class'];
// works and does does not segfault
if (strlen($calledby[1]['class'])) $caller = $calledby[1]['class'];
else $caller = $calledby[0]['class'];
# arguments are required
if (!func_num_args()) { return; }
# fill variables with argument contents if exists
$variables = (func_num_args() == 0) ? NULL : (is_array(func_get_arg(0)) ?
func_get_arg(0) : NULL);
Expected result:
----------------
I expect that Apache will not SEGFAULT
