big loop with big array

I have this big array and this big {for} loop to fill this array the loop reads a soundfile, and writes it to the array, the sound data is simple, 3minutes of 10hz constant so the sound data should be something that starts 0,1,2,3,4,...65534 then goes down and up and down again and again but debuggin i found that when it gets aproximately to the 200 loop the data that reads will stay the same so it will fill the array with the same value from that point until it finishes loop. the soundfile can be changed to another music that has same format and the same happens, why? [source lang="cpp"] D3DXVECTOR4 dd[7935489]; //the big array, it is located up in the head of the program. //Data of sound BYTE id[40]; unsigned int ivb; unsigned short p1[2]; //right and left 1 unsigned short p2[2]; //right and left 2 FILE * fp; fp = fopen("12.wav","r"); fread(id,sizeof(BYTE),40,fp);//read unessesary info of sound fread(&ivb,sizeof(unsigned int),1,fp);// read the sized of the data unsigned int ss= ivb/4;// calculate num of samples unsigned int i; for(i=0;i < (ss/2);i++)//fill part of the array with all sound data { fread(p1,sizeof(unsigned short),2,fp); fread(p2,sizeof(unsigned short),2,fp); dd=D3DXVECTOR4(float(p1[0]),float(p1[1]),float(p2[0]),float(p2[1])); }[/source]
