Bug description: Unable to allocate memory with big jpeg files
Description:
------------
I wrote a script that uses GD to slice big jpeg files (about 50mb,
21600x21600) into small 100x100 jpeg.
To make this, I have to open these big files and I use the function
imagecreatefromjpeg.
While loading (HDD is working), I receive this error:
FATAL: emalloc(): Unable to allocate 86400 bytes
I have tested different values of memory_limit in php.ini ( and with
--enable-memory-limit) even the unlimited value of -1: always the same
error.
This error happens only with very big jpeg files (37mb and 47mb), not with
about 4mb jpeg.
Reproduce code:
---------------
Launching PHP in Command Line mode under Windows XP:
php "myscript.php" --enable-debug --enable-memory-limit
The PHP Code is very simple :
$img = imagecreatefromjpeg("bigfile.jpg");
Expected result:
----------------
Opening of the image.
Actual result:
--------------
FATAL: emalloc(): Unable to allocate 86400 bytes
