WARNING: problem in alloc set ExprContext: detected write past chunk end in block 0x14ce680, chunk 0x14ce718

I found traces of bad-looking warnings in the output from garden test, in ST_AsGML:

WARNING:  problem in alloc set ExprContext: detected write past chunk end in block 0x267d370, chunk 0x267d408
CONTEXT:  SQL statement "SELECT ST_AsGML(2, foo1.the_geom, 5, 5, 'monkey', 'monkey') As result FROM ((SELECT ST_SetSRID(ST_Point(i,j),4326) As the_geom FROM (SELECT a*1.11111111 FROM generate_series(-10,50,2) As a) As i(i) CROSS JOIN generate_series(40,70, 5) j ORDER BY i,j )) As foo1 LIMIT 3;"

I think this one got fixed at r13456 in #3104
