libxml related crash on git head

-----BEGIN PGP SIGNED MESSAGE-----
Hash: RIPEMD160

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 while processing 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.
