C++ code which crashes g++

g++ runs out of memory and crashes, when the following simple code is compiled

#include <array>
const int ARR_SIZE = 0x10000;   // 64 K

struct A {
  char whatever;
  A() { whatever = 0; };   // removing constructor removes the problem
};

class B {
  std::array<std::array<A, 8>, ARR_SIZE>  values;
public:
  B();
};

B::B() : values{}   // removing explicit initialisation of values (i.e.
removing ": values{}") removes the problem
{}

int main() {  return 0; }
