Meanwhile, it dawned on me what you meant, so I added an #undef 
statement into the innermost loop:

   #while (g < fac & f+g <= frames)
     #declare P_Pixel=
     pigment
     {
       image_map
       {
	#declare filefull =  concat(path, file, str(f+g, -6, 0), ".png");
	png filefull
       }
     }
     #declare sumcolvect=sumcolvect+eval_pigment(P_Pixel, <0.5, 0.5, 0>);
     #undef P_Pixel
     #declare g=g+1;
   #end

...but all I get now is just another error message:

*** Error in `povray': free(): invalid size: 0x00007f91d007bc30 ***

See you in Khyberspace!
