Against an unmodified HEAD (17fa3e8), I got a segfault in the hot standby. Using the attached files, I start the test case like this:
nice sh do_nocrash_sr.sh >& do_nocrash_sr.err &
And start the replica like:
rm -r /tmp/data2_replica/ ;
psql -p 9876 -c "select pg_create_physical_replication_slot('foo')";
~/pgsql/pure_origin/bin/pg_basebackup -p 9876 -D /tmp/data2_replica -R -S
foo;
~/pgsql/pure_origin/bin/pg_ctl start -D /tmp/data2_replica/ -o "--port=9874"
After less than a minute, the replica fails.

'unused' is NULL at that point.
