-Status: Open
+Status: Bogus
Bug Type: Reproducible crash
Operating System: MAC OS 10.2.6
PHP Version: 4CVS-2003-09-06 (stable)
New Comment:

Can not reproduce with a script that has $x=1 about 500'000 times. Only
thing I get is:

Allowed memory size of 8388608 bytes exhausted at
/usr/src/web/php/php4_3/Zend/zend_opcode.c:48 (tried to allocate
11796480 bytes)

I suggest you use '--enable-memory-limit' configure option and set the
'memory_limit' directive in php.ini to a reasonable amount. This will
prevent any stupid scripts like this from crashing.

Description:
------------
I have tested this with the 4.3.2 and
4.3.3 official releases as well. I have not tried any
earlier releases. I have tried with the command line or
as an Apache 1 or Apache 2 module all with the same result.

I used no extensions or modules for the builds in all
cases.

Apparently the bug does not occur for Windows XP Pro and
likely
some other operating systems. I was told this by some users
of a PHP forum who tried their own test scripts.

The result of memory_get_usage() placed on a script one
line shorter than the crash length returned around 1MB.

Thank you.

Reproduce code:
---------------
<?php

/*presumably any long script that consumes enough memory will cause the
problem*/

/*this assignment done about 10000 times*/
$x = 1;

?>

Expected result:
----------------
Nothing but a clean run through.

Actual result:
--------------
The backtrace from the STABLE snapshot cli was...
