Description:
------------
Hi,

i am drawing images using Apache 2 and GD2. Whenever I draw two images at the same time, there is a locking problem with the True Type Font. In some cases Apache 2 crashes, in others php throws a failure.

Sven.

Please provide a short example.

here is some code for reproducing the error. Note, it works sometimes, but mostly there are errors.

--- code for sample.php ---

<?php
header ("Content-type: image/png");
$im = @ImageCreate (200, 200)
      or die ("Cannot create image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
$font = "c:/windows/fonts/arial.ttf";

for ($i=0; $i<360; $i+=5) {
  ImageTTFText ($im, 12, $i, 50, 50, $text_color, $font, 
               "Draw sample text.");
}
ImagePNG ($im);
?>


--- end of sample.php ---

--- code of reproduce.php ----

<html>
<head>
</head>
<body>
<?php
 for ($i=0; $i<50; $i++) {
   echo '<img src="sample.php?'.$i.'"><br>'."\n"; 
 }
?>
</body>
</html>


-- end of reproduce.php ---


Both files are in one directory. Calling reproduce.php will bring up the error.

This is a problem related to the freetype lib. Already reported here. We cannot fix this issue.
