PostgreSQL crashes every time if I insert more than ~280 rows containing a GEOGRAPHY POINT in a table containing a GIST index

[renefournier]

Creating a table with a GIST index on the GEOGRAPHY(POINT,4326) column, and then inserting hundreds rows, PostgreSQL will crash every time at row 284 (changing the order of the rows will affect at which row the crash occurs — appears to be dependent on cumulative data size). If I remove the index, the crash never occurs.
