Thanks for interesting results!

According to the logs, walreceiver receives 'c' message (which is invalid
for walreceiver) though walsender doesn't send it. So, next, I should
diagnose more carefully the messages between those processes.
Please test synch-rep again and report the following information.

* server log
* walreceiver_trace.out
* netstat -nap (before and after replication crashes)
* tcpdump -i lo -n tcp
