Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

Unfortunately Freetype functions are not thread safe, so in a threaded
enviroment problems such as the ones you are experiencing will occur.

Also, in addition to the "Problem loading glyph in..." problems, I get
some "Problem setting text size" errors as well.

And, this problem goes away every time you restart apache, but that
means I have to keep restarting it to make it work.

If I put an "@" in front of the errornous lines, it doesnt give me a
Red X but just the image without the text on it.

Description:
------------
Every so often, I get this output from my file:

<br />
<b>Warning</b>:  imagettftext(): Problem loading glyph in
<b>g:\hostroot\a0007\default\wwwroot\images\button.php</b> on line
<b>81</b><br />

And so ofcourse, the image displays as the notorious red X in IE

Reproduce code:
---------------
<?php

define("FONTFILE", "./arial.ttf");
define("FONTSIZE", 8);
define("WIDTH", 145);
if ($_GET["bottom"] == 1) {
	define("HEIGHT", 20);
	$mod = -1;
}
else {
    define("HEIGHT", 19);
	$mod = 0;
}

$im = imagecreate(WIDTH,HEIGHT);
$black = imagecolorallocate($im, 0, 0, 0);

//This part of the code was omited because of its length. It basically
is a bunch of imagesetpixel(), imageline(), and imagefilledrectangle()
functions to give this button a 3d bevel.

//text
$textdata = imagettfbbox(FONTSIZE, 0, FONTFILE, $_GET["text"]);
$bbox_h = $textdata[1] - $textdata[7];
imagettftext($im, FONTSIZE, 0, 4, 14, $black, FONTFILE,
$_GET["text"]);

imagepng($im);

?>

Expected result:
----------------
Most of the time this works, but it randomly gives the error described
above.
This problem only occurs on PHP 4.3.2 and worked fine under 4.2.3.
