It includes 5*5 times "size 64" memory leaks, which correspond to 5 times testinitiiogainscale() calls with gtstestgains size 10 (10*size(int)) and gtstestitimes size 5. It also includes 5*1 times "size 16" memory leak, which correspond to one time _testinitiiogainscale() call with gtstestgainsgainlow size 3 (3*size(int)) and gtstestitimes size 5. The reason is that the pertimegains[i] is not freed which is allocated in the "gts->numitime" for loop in iiogtsbuildavailscaletable().
