This code:

<? 
    Header( "Content-type: image/gif"); 
    if(!isset($s)) $s=11; 
    $size = imagettfbbox(10,0, "/usr/local/fonts/TIMES.TTF",$text); 
    $dx = abs($size[2]-$size[0]); 
    $dy = abs($size[5]-$size[3]); 
    $xpad=9; 
    $ypad=9; 
    $im = imagecreate($dx+$xpad,$dy+$ypad); 
    $blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF); 
    $black = ImageColorAllocate($im, 0,0,0); 
    $white = ImageColorAllocate($im, 255,255,255); 
    ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black); 
    ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white); 
    ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black,  "/usr/local/fonts/TIMES.TTF", $text); 
    ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white,  "/usr/local/fonts/TIMES.TTF", $text); 
    ImageGif($im); 
    ImageDestroy($im); 
?>

It apparently is this line:
  $size = imagettfbbox(10,0, "/usr/local/fonts/TIMES.TTF",$text); 

causes A segmentation fault in apache's error_log, and of course the image is not displayed on both php 3.0.7, and 3.0.9.

the php.ini is blank

do-conf:
./configure --with-apache=../apache_1.3.6 --with-gd --with-mysql --with-ldap=/usr/local --with-imap --with-zlib
 --enable-debug=no
