The following query causes a stack overflow in the JSON parser:

WITH RECURSIVE c(x) AS (VALUES(1) UNION ALL SELECT x+1 FROM c WHERE x<400000)
SELECT json_valid(group_concat('[', '')) FROM c;

This problem was reported on the SQLite mailing list by Ralf Junker and is based on the n_structure_100000_opening_arrays.json test case from the JSONTestSuite.
