Comment (by karme):

 Replying to [comment:3 glynn]:
 > My inclination is to apply the patch. Unlike most GRASS memory "leaks",
 this one could be significant. I.e. if it leaks memory for each row
 fetched, it would impose a limit on the amount of data retrieved from a
 query.

 Well it does not leak memory for each row fetched, but for each query. But
 at the moment I am writing a v.out.osm that in the end does a query for
 each line => you run out of memory quickly. It would be really nice to get
 this fixed - maybe also in the stable branch? and maybe in debian/lenny?

 A quick grep for db_open_select_cursor gives many hits and some of them
 are in a inner loop. For example: v.out.ogr (in mk_att), d.vect (attr.c),
 v.label, ...
