Why do you need this option?

+
+#define KNOWN_FILE_SIZE 30

This is kind of strange: some information goes to test_fstat.stdout while the
filesize is hardcoded in source. Why not print it out and add to
test_fstat.stdout ?

+
+int main(int argc, char** argv) {
+  struct stat st;
+  FILE* file;
+  int fd;
+  if (2 != argc) {
+    printf("Usage: sel_ldr test_fstat.nexe test_stat_data\n");
+    return 1;
+  }
+  st.st_size = 0;
+  printf(
+      "%d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d+%d %d\n",
+      offsetof(struct stat,st_dev),sizeof(st.st_dev),
