Well, the trace shows exactly what I thought was happening: each time
the startup process hits one of these:

it sends a SIGTERM to kill the walreceiver, because it thinks this
indicates a walreceiver problem. Then we launch another one and manage
to process a few more WAL records, lather rinse repeat.
So it's interesting that this only happens with a particular gcc version,
because it's not apparent to me why it works properly for anybody.
Isn't hitting a zero record length an expected case when we run ahead of
the amount of WAL produced by the master?
