#40800 [NEW]: cannot disable memory_limit with -1
From: php at vicaya dot com
Operating system: Linux 64-bit
PHP version: 5.2.1
PHP Bug Type: Reproducible crash
Bug description: cannot disable memory_limit with -1
Description:
------------
According to the documentation: http://us2.php.net/manual/en/ini.core.php
"Note that to have no memory limit, set this directive to -1."
But the code use more than 4GB virtual memory crashes with "Fatal error:
Allowed memory size of -1 bytes exhausted (tried to allocate 605 bytes) in
..." anyway.
Reproduce code:
---------------
<? count(file("a_10GB_file")) ?> // not production code :)
on a machine with enough ram and swap space.
Expected result:
----------------
number of lines in "a_10GB_file".
Actual result:
--------------
"Fatal error: Allowed memory size of -1 bytes exhausted (tried to allocate
605 bytes) in ..."
Suspect that memory limit directive is still a 32bit unsigned integer
(size_t) and -1 is converted to 4G-1.
