--- Comment #3 from ktkachov at gcc dot gnu.org ---
A slightly adjusted testcase is:

#include <functional>
#include <iostream>

struct C
{
  void
  doCb ()
  {
    size_t dummy_a = 1;
    std::cout << "";
    auto tmp = this;
    std::function<void()> f;
    f = [this, &dummy_a]() {};
    f = [this, tmp]() {
      if (this != tmp)
        __builtin_abort ();
    };
    f ();
  }
};

int
main ()
{
  C c;
  c.doCb ();
}

This aborts on arm at -O2 but not at -O1
