Operating system: Linux
PHP version: 5.5.8
Package: GD related
Bug Type: Feature/Change Request
Bug description:32-bit integers used internally
Description:
------------
Even when using PHP with GD on a 64-bit machine, the 4 GB memory limit
rears its ugly head.
Thus, we have problems like this one:
https://stackoverflow.com/questions/20614686/gd-warning-product-of-memory-allocation-multiplication-would-exceed-int-max
I would propose going in and updating the integer definitions to
accommodate 64-bit processors and its larger memory space, but GD isn't
my forte so I'm not sure if I would break all of the things if I went in
and patched it.
Test script:
---------------
echo PHP_INT_MAX . '<br/>';
echo 174400 * 249600 . '<br/>';
$img = imagecreatetruecolor(174400, 249600);
Expected result:
----------------
9223372036854775807
43530240000
Warning: imagecreatetruecolor(): gd warning: product of memory
allocation multiplication would exceed INT_MAX, failing operation
gracefully in
/home/bartek/Documents/WWW/WOF/application/controllers/EditorController.php
on line 5
Actual result:
--------------
<b>Parse error</b>: imagecreatetruecolor(): product of memory
allocation multiplication would exceed INT_MAX, failing operation
gracefully
