Comment (by lnicola):

 @latot FWIW, I ran your test case (the one calling
 {{{TopoGeo_AddPolygon}}}) with my proposed patch and it didn't crash, the
 memory usage stays unchanged and the tests still pass (except the raster
 ones which I disabled because they use a wrong path even after {{{make
 distclean}}}.
