error: fixup must be 8-byte aligned

[fxcoudert]

Taken from gcc.c-torture/execute/20000822-1.c:

$ cat 20000822-1.c 
#include <stdlib.h>

int f0(int (*fn)(int *), int *p) { return (*fn) (p); }

int f1(void) {
  int i = 0;
  int f2(int *p) {
    i = 1;
    return *p + 1;
  }
  return f0(f2, &i);
}

int main() {
  if (f1() != 2)
    abort ();
}
$ ./bin/gcc 20000822-1.c
/var/folders/5b/7mrgq6j55b51p7ztj1r3gv400000gq/T//cc8QdllL.s:70:2: error: fixup must be 8-byte aligned
        ldr     x2, [x1, LTRAMP0@GOTPAGEOFF];momd
        ^

Can be further reduced to:

$ cat a.c
int f0(int (*fn)()) { return 0; }
int f1() {
  int f2() { return 1; }
  return f0(f2);
}
$ ./bin/gcc a.c
/var/folders/5b/7mrgq6j55b51p7ztj1r3gv400000gq/T//cczkuEjo.s:55:2: error: fixup must be 8-byte aligned
        ldr     x2, [x1, LTRAMP0@GOTPAGEOFF];momd
