This problem seems to have first occurred sometime between 20200507 and
20200508.

Source code attached. I'll have my usual go at reducing the code.

Reduced code:

struct a {
  struct {
    struct {
      int b
    } c
  }
};
struct d {
  struct {
    int e
  } f
} g(h) {
  struct a *i;
  struct d *j = &h;
  i->c.b = j->f.e;
}

    testsuite: Fix up gcc.dg/asan/pr95051.c testcase [PR95051]

    asan.exp adds -fsanitize=address which is incompatible with
-fsanitize=kernel-address,
    so we need to disable it first.

    Simplify test-case options.
