Comment(by pramsey):

 I'd expect trunk to blow chunks too,

 http://trac.osgeo.org/postgis/browser/trunk/postgis/geometry_estimate.c?rev=11274#L938

 the edit means that VARSIZE is being called on... something? Just pfreeing
 the geom at the end of the loop might be the preferred approach. Or, find
 out what we're supposed to be saving into stawidth, since that's black
 magic.
