Previous Comments: ------------------------------------------------------------------------ [2002-04-25 21:23:20] daniel@pressure.net.nz <?php header ("Content-type: image/png"); $im = @imagecreate (50, 100) or die ("Cannot Initialize new GD image stream"); $background_color = imagecolorallocate ($im, 255, 255, 255); $text_color = imagecolorallocate ($im, 233, 14, 91); imagestring ($im, 1, 5, 5, "A Simple Text String", $text_color); imagepng ($im); ?> generates a reproducable segfault in DSO, CGI and CLI versions. GD is version 1.8.4, although segfaults also occurred with 2.0.1. Libpng is 1.2.1, zlib is 1.1.4. Compiling PHP 4.1.2 identically does not produce the segfault. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16841&edit=1
