The following code is said to repeat the crash on Win32 , works fine on
Linux. Unfortunately I don't have access to a Win32 system to be able
to repeat.
The reproduce script was submitted by dietrich at ganx4 com
<?php
$string = "i crash.";
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
$im = @imagecreate ($width,$height);
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 0, 0,0);
imagestring($im, $font, 0, 0, $string, $text_color);
imagejpeg($im,'test_sample.jpg');
?>

here is a simple reproduction script.
the crash only occurs when writing the image to file, and is
reproducible 100% of the time.
<?php
$string = "i crash.";
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
$im = @imagecreate ($width,$height);
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 0, 0,0);
imagestring($im, $font, 0, 0, $string, $text_color);
imagejpeg($im,'test_sample.jpg');
?>

another comment: this is a regression. our code works fine in 4.3.2,
but is broken b/c of this so we cannot upgrade.
here's a quote from the jpgraph people:
"There seems to be a bug with some versions of PHP on Windows. It has a
(known) problem with simultaneous accessing the TTF libraries, (perhaps
some thread-safety issues ?). No known workaround exists (apart from
moving away from Win2000) as far as I'm aware."
is anyone familiar w/ this issue?
thanks, d.

sorry, i left a piece of information out: php.exe is crashing for me,
not the webserver. that's the only behavioral difference between what
i'm experiencing from the original bug report.
every time i load my graph scripts, php.exe goes boom.
