Question successively subtracting -> memory limit

Hi!I wrote this:

    for (int i=0;i<=7;i++){
       for (int j=0;j<=7;j++){
            G4double pxl_PosZ = 0.0*mm;
            G4double pxl_PosX = 2.88*(i-3.5)*mm;
            G4double pxl_PosY = 2.88*(j-3.5)*mm;
            G4ThreeVector hole_pos = G4ThreeVector(pxl_PosX,pxl_PosY,pxl_PosZ);
            char numHole[4];sprintf(numHole,"%d%d",j+1+(i*8));
Mask_solid = 
new G4SubtractionSolid(numHole,Mask_solid,MaskHole_box,0,hole_pos);}}

in order to make a 8*8 array of holes on the mask. I could make at most 5 rows of holes, which was 40 times recursively using the function

the_mask = new G4SubtractionSolid(..., the_mask, the_hole, ...)

, without problem. If I made more, it just caused memory problem and stocked there. Do you have any better way to do this without so many "new" declaration occupies memory? Thank you all in advance!
