libxml related crash on git head

I'm getting HEAD errors on my build farm animal fennec. 
I've narrowed it down to this test case:

greg=# CREATE TEMP TABLE boom AS SELECT 'ABC'::bytea;
greg=# SELECT table_to_xml('boom',false,false,'');
server closed the connection unexpectedly       This probably means the server terminated abnormally       before or
whileprocessing the request.
 
The connection to the server was lost. Attempting reset: Failed.

Specifically, it's only the bytea data type, with that function. The 
boolean arguments do not make a difference. I cannot reproduce this on 
other boxes, so I suspect it may be a libxml bug. This server is running 
libxml2 version 2.7.2: we require >= 2.6.23. I've tried manually installing 
a newer version of libxml, but make fails with:

ld: crtbeginS.o: No such file: No such file or directory
libtool: install: error: relink `libxml2mod.la' with the  above command before installing it

I don't have time/inclination to track down why the make is failing, but 
may have some time to run any Postgres-specific tests, if anyone wishes 
me to.

Oh, I looked at that the other day.  The animal started failing after
you installed a new libxml in /usr/local.  It looks like it is compiling
against the /usr/local copy but still executing against the .so in
/usr/lib64.  Linuxen are not terribly friendly to ad-hoc library
installs --- in particular, if you don't tell ldconfig to look in
/usr/local, it's never gonna work.

I'd suggest just dropping the non-default libxml installation, then.

BTW, right at the moment you seem to have git issues, too.
        regards, tom lane

Ah, okay, that makes sense. So MediaWiki wanted a new version but 
libxml was being *really* problematic so I abandoned the install, but 
I guess it left some pieces around. I will see if I can clean it up.

Thanks, I will check on that.
