Strangely, in my functioning configuration (with apr and apr-util
downgraded to 1.2.x) appears to already be at odds with php as far as
the libmysqlclient_r.so is concerned. (ldd output below)
I'll try getting them all to use the same one later tonight. But it's
it's strange that they appear to be differing already and are running
just fine.
I saw that one solution might be to symlink /usr/lib64/
libmysqlclient.so.15.0.0 -> mysql/libmysqlclient_r.so.15.0.0 and
recompile php. Would that work? I don't compile directly from source
-- i use gentoo portage (like bsd ports) and i'm not really fond of
patching and install it myself because i often screw up other stuff.

Hi,

I ran in to a problem where I couldn't seem to use apr and apr-util
1.3.x because Apache httpd would segfault every time. I found bugs

clear to me that this info was getting where it needed to be... the
apr developers, right?
It seemed that everyone who had the problem downgraded to 1.2 and
left it at that.
this could be due to php-mysql linking to libmysqlclient.so and
apr-util-mysql linking to libmysqlclient_r.so (you can verify that
with ldd). Since both libraries use the same symbols and symbol
versions, all kinds of things can go wrong when both are loaded into
the same process.
You can try compiling php with libmysqlclient_r.so, e.g. by using this
patch
http://svn.debian.org/wsvn/pkg-php/php5/trunk/debian/patches/force_libmysqlclient_r.patch?op=file&rev=0&sc=0
and recreating configure. There is some discussion about this issue at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=450535
