Summary: imagettfbbox randomly don't work
Status: Assigned
Type: Bug
Package: GD related
Operating System: Debian GNU/Linux 5.0
PHP Version: 5.3.2
Assigned To: geissert
New Comment:
I tried with the following versions and with all of them the result is
the same:
4.1.2, 4.2.4, 4.3.4, 4.4.3
So it's a bug on libgd's side. Will ask Sean as he is the maintainer at
Debian.

Strange that you mention that it works with gcc 4.1.2. Last I heard
5.3.x failed to build with that version (don't know what arch was that,
though).
Will take a look at it later. FWIW, a test related to imagettfbbox is
reproducibly failing (with the same results on all archs):
ext/gd/tests/bug48801.log:
---- EXPECTED OUTPUT
(-1, 15)
(155, 15)
(155, -48)
(-1, -48)
---- ACTUAL OUTPUT
(1, 15)
(163, 15)
(163, -48)
(1, -48)
---- FAILED
And that was with 4.4.3 (same results without optimisation). Has anyone
tried to reproduce it with the same or similar versions of gcc from
another distribution?

So I have find the origin of the problem : "GCC".
This problem appear if you compile PHP 5.3.2 width GCC 4.3.2 on Debian
32 bits. For fix the problem you must compile PHP 5.3.2 width GCC 4.1.2.

So I have add debug line and i find origin of bug :
View my previous script an modify width this line :
$tab =
imagettfbbox(8,0,Config::getCons('PATH_CACHE').'font/verdana.TTF',
$texte);
$text_x = (55-($tab[2]-$tab[6]))/2;
$text_y = (15-($tab[1]-$tab[5]))/2+9;
file_put_contents(Config::getCons('PATH_CACHE').'log_font.txt', $text.'
x:'.$text_x.' y:'.$text_y.'
imagbox:'.json_encode($tab)."\n",FILE_APPEND);
The result :
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:33554459 y:12.5
imagbox:[-1,-1,-33554433,-1,-33554433,-9,33554430,-9]
x:33554459 y:12.5
imagbox:[-1,-1,-33554433,-1,-33554433,-9,33554430,-9]
x:33554459 y:12.5
imagbox:[-1,-1,-33554433,-1,-33554433,-9,33554430,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
x:33554459 y:12.5
imagbox:[-1,-1,-33554433,-1,-33554433,-9,33554430,-9]
x:12 y:12.5 imagbox:[-1,-1,30,-1,30,-9,-1,-9]
So the problem is located on imagettfbbox funtion, it give wrong value
for x position.
