What it looks like to me is something clobbering memory, eg writing more
data into a palloc'd memory chunk than will fit; which results in
overwriting malloc's own data structures, causing malloc to complain
when it notices.
Whether it's your bug or something wrong in the beta is hard to say.

--enable-cassert would probably help more, since it would turn on some
clobber-detection support in PG.
