I have tried this with 4.3.2RC1 and the latest development
snapshot.
Configure options:
./configure --with-apxs --with-zlib --with-bz2 --with-gd
--enable-gd-native-ttf --with-mysql=/usr --enable-sockets
--prefix=/usr --with-ttf --enable-ftp --with-jpeg-dir=/usr
--with-freetype-dir=/usr --enable-debug
The following is the script that triggers the problem:
<?
/* Vertial Label maker */
$im = ImageCreate(14,150);
$cBlack = ImageColorAllocate($im, 0, 0, 0);
$cWhite = ImageColorAllocate($im, 255, 255, 255);
$cBlue = ImageColorAllocate($im, 100, 100, 255);
if($lk == 1)
{
ImageTTFText($im, 10, 90, 11, 150, $cBlue,
"/var/www/prime/common/arialbd.ttf", $in);
} else {
ImageTTFText($im, 10, 90, 11, 150, $cWhite,
"/var/www/prime/common/arialbd.ttf", $in);
}
Header("Content-type: image/png");
ImagePng($im);
ImageDestroy($im);
?>
This script is called a number of times in a page, with
(for example): vl.php?lk=0&in=Bonus+30-Mar-2003
Running gdb on apache -X, the crash occurs:
Program received signal SIGSEGV, Segmentation fault.
