#49866 [NEW]: Making reference on string offsets crashes PHP
From: doctorrock83 at gmail dot com
Operating system: Linux
PHP version: 5.3.0
PHP Bug Type: Scripting Engine problem
Bug description: Making reference on string offsets crashes PHP
Description:
------------
When making a reference on a string offset and changing it, PHP5.3 crashes
with segfault, but PHP 5.2, 5.1 and 5.0 throws errors.
I know that it's a bad PHP programming than thinking PHP is C, the fact is
that this behavior gives PHP errors in 5.2/5.1/5.0 branches, but segfaults
5.3.0 release.
Reproduce code:
---------------
<?php
$a = "string";
$b = &$a[1];
$b = "f";
echo $a;
Expected result:
----------------
sfring
But PHP5.2.0 and 5.0.0 tell :
"Fatal error: Cannot create references to/from string offsets nor
overloaded objects in XXX"
PHP 5.1.0 tells:
"Fatal error: fatal flex scanner internal error--end of buffer missed in
XXX"
PHP5.3 segfaults
Actual result:
--------------
segmentation faults
