#100 Apache segfaults under Mac OS X Server 10.3

[Aaron Jensen]

apache 1.3.29
php 4.3.6
mmcache 2.4.6
Mac OS X Server 10.3.3

I usually get 20 - 30 crashes a day. When I disable mmcache and
restart my server, the crashes go away. When I just disable
mmcache, the crashes continue. I have tried enabling mmcache as
both a zend and php extension. I have tried turning off
compression. Nothing seems to work.

I run about a dozen web sites, some running WordPress, Gallery,
and SquirrelMail. I have searched through the access logs looking
to see if there was any corelation between the crashes and a
specific script being run. There isn't. Sometimes the crashes
happen when no requests have been made within a few seconds.

Here is a snippet from my error_log:

Any chance you can rebuild PHP and Turck MMCache with debugging
turned on? I'll take a look at this, but I need a bit more info to get
started.

Are the scripts that are called last before the crash specific to one
package like SquirrelMail, WordPress or Gallery?

After installing PHP 4.3.9, these crashes have gone away. I read the
release notes to that version, and found this: "Fixed bug #29349
(imagecreatefromstring() crashes with external GD library)." I'm pretty
sure that was the bug I was encountering. (But it was kind of weird,
since it only ever showed up when turck-mmcache was enabled.)
