The receive function of hstore was not able to handle correctly duplicate key values when a new duplicate links to a NULL value, where a pfree() could be attempted on a NULL pointer, crashing due to a pointer dereference. This problem would happen for a COPY BINARY, when stacking values like that: aa => 5 aa => null The second key/value pair is discarded and pfree() calls are attempted on its key and its value, leading to a pointer dereference for the value part as the value is NULL. The first key/value pair takes priority when a duplicate is found. Per offline report.
