The proximate cause seems to be that _bt_newroot isn't bothering to
fill the buffer_std field here:
/* Make a full-page image of the left child if needed */
rdata[2].data = NULL;
rdata[2].len = 0;
rdata[2].buffer = lbuf;
rdata[2].next = NULL;
which is indeed an actual bug, but the only consequence would be poor
compression of the full-page image (if the value chanced to be zero),
so it's not much of a problem.
What remains unclear is how come this only fails once in a blue moon.
Seems like any valgrind run of the regression tests should have caught it.
