Status: Open
Bug Type: Reproducible crash
Operating System: Windows 2000 SP3
PHP Version: 4.3.6
New Comment:
This happens to me as well. What is odd in my case is when my webpage
(intranet site) has been idle for more than a few hours (like
overnight), the next graph generation session will come back with one
of the graphs throwing a JPGraph "TTF Font Error". On the monitor of
the server box there will be a "Message Box" stating that Apache has
crashed and a log file has been created. I hit "OK" but never have to
restart Apache and all is fine. Even while this "Message Box" is
present, the server will still generate pages with graphs. I've looked
all over for this log file it said it created and have never found one.
I resubmit the request and all graphs are fine. Everything works
flawlessly as long as the server is kept fairly active.
Apache 1.3.24
PHP 4.3.3 as a SAPI module
Windows 2000 SP3

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.
