#28084 [Com]: Crashes when fonts are accessed
ID: 28084 Comment by: dietrich dot ayala at foundstone dot com Reported By: doormat at sequence-omega dot net Status: Open Bug Type: Reproducible crash Operating System: Windows 2000 SP3 PHP Version: 4.3.6 New Comment: I compiled the GD2 module against the most recent stable versions of freetype, libpng, libjpeg and zlib, and this problem went away. Previous Comments: [2004-05-06 16:59:23] mmoria01 at sprintspectrum dot com 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.

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. The remainder of the comments for this report are too long.

And if you want us to debug this, provide a short (max 10 lines!) reproducing script (or get the JPGraph author to do this). [2004-04-21 09:12:04] [EMAIL PROTECTED] Not enough information was provided for us to be able to handle this bug.

Thank you for your interest in PHP. [2004-04-21 00:44:49] doormat at sequence-omega dot net Description: Using the JPGraph library, when any graphs are created at the same time, and they use TrueType fonts, apache will crash. Switching away from the use of TrueType fonts helps, but occasional crashes still happen. The developer of JPGraph said the problem was in the underlying PHP implementation (http://jpgraph.fan-atics.com/viewtopic.php?t=1752) so I'd thought I'd file a bug report to see if ya'll could figure it out. Reproduce code: --- Too long to post... download sample code from http://www.aditus.nu/jpgraph/ and put multiple graphs (especially ones that use TTFs) on one page and load it up and apache should crash. -- Edit this bug report at http://bugs.php.net/?id=28084edit=1
