Crash due to memory leak?

[biodiv]

When I call functions like ST_Centroid or ST_ConvexHull on smaller Polygons mysql crashes. Query:

SELECT count(*), AsText( mysql.ST_Centroid(coordinates)) 
FROM TABLE WHERE coordinates IS NOT NULL 
AND Within( coordinates, GeomFromText( 'POLYGON ((-22.5000000000000000 61.6063959999999966, -22.5000000000000000 55.7765729999999991, -33.7500000000000000 55.7765729999999991, -33.7500000000000000 61.6063959999999966, -22.5000000000000000 61.6063959999999966))' ) )

Is it possible to allocate more memory to those functions? I alreade increased the values in my.cnf but without success.

Hi,
I think that decreasing the values of my.cnf you give more options to the library to get more memory.
How did you deduce that it was a memory problem ?

Have you made any test with small table ? Perhaps it's a problem with an specific geometry ..
