Please post your test program.  Mine works fine:

#include <stdio.h>

char buf[1024];

main()
{
  int rv;
  FILE *f = fopen("afile.bin", "rb");

  rv = fread (buf, sizeof(char), 128, f);
  printf("ask 128 got %d\n", rv);

  rv = fread (buf, sizeof(char), 64, f);
  printf("ask 64 got %d\n", rv);

  rv = fread (buf, sizeof(char), 128, f);
  printf("ask 128 got %d\n", rv);

  fclose(f);
  exit(0);
}

ask 128 got 128
ask 64 got 64
