Access violation reading location location 0x1D5C4C2F

Access violation reading location location 0x1D5C4C2F

This function is throwing an access violation when reading raw pixel
values and I can't figure out why. Can consider this as the only part of
my code running, I've run this solo with the same result.
string filenames[]={"firstclick.raw",
"secondclick.raw","thirdclick.raw","fourthclick.raw","fifthclick.raw","sixthclick.raw","seventhclick.raw","eighthclick.raw"};
FILE *file;
int height= 750, width = 453, bbp=3;
unsigned char ****images;
images = (unsigned char ****)malloc(sizeof(unsigned char ***)*8);
for(int j = 0; j<8; j++){
images[j] = (unsigned char ***)malloc(sizeof(unsigned char**)*height);
for(int i = 0; i<height; i++){
images[j][i]= (unsigned char **)malloc(sizeof(unsigned char*)*width);
for(int k = 0; k<bbp; k++)
images[j][i][k]= (unsigned char *)malloc(sizeof(unsigned
char)*bbp);
}
}
for (int i = 0; i<8; i++){
if (!(file=fopen(filenames[i].c_str(),"rb"))){
cout << "Cannot open file: "<<filenames[i].c_str() <<endl;
exit(1);
}
fread(images[i], sizeof(unsigned char), height*width*bbp, file);
fclose(file);
}
