I've got a few MediaWiki installations on a my FreeBSD 10.1 / Apache
2.4.16 / PHP 5.6.14 server.  The home pages of these sites are OK, but
when you click the "Log In" link, the style sheet fails to load, and
in the web server error log I see:

AH00052: child pid 32320 exit signal Segmentation fault (11)

The login page is still functional, but when I log in and go to edit a
Wiki page, I get the same segmentation fault while loading the style

I found this page:


which mentions a problem with pcre.backtrack_limit, but my
installation has that set to 1000000 so I'm guessing that's not the
case (and it seems weird that such a setting could cause a segfault

Is this a known issue?  Is there an easy fix?  Would it be helpful to
provide xhprof output?  (I didn't want to go through the hassle of
setting that up until I was sure this wasn't a known issue.)

Thanks for any help you can give!
