Description:
------------
When i open an php script that uses GD it shows an segmentation fault in error.log
Server software: Apache/1.3.26 (deb package) (Unix) Debian GNU/Linux PHP/4.3.8
The script is comming from php.net so i dont supose there's an error in it.
I included /usr/local/lib/php in php.ini and i added extension = gd.so
'./configure' '--with-jpeg-dir=../jpeg-6b/' '--with-pdflib' '--with-tiff-dir=../tiff-v3.6.1/' '--with-png-dir=../libpng-1.2.5/' '--with-zlib-dir=../zlib-1.1.4/' '--enable-static-pdflib' '--enable-gd-imgstrttf' '--with-gd' '--with-mysql' '--with-apxs' '--enable-fast-cgi-redirect' '--with-freetype-dir=/usr/local/freetype2/' '--with-iconv' '--with-gettext'
Reproduce code:
---------------
<?php
header("Content-type: image/png");
$string = $_GET['text'];
$im = imagecreatefrompng("banners/bannerxplose.test.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);
?>
Actual result:
--------------
I only get, Cant find server and in error.log i find
