  throwing from (singleton) constructor gives segmentation fault

Status in “gcc-defaults” package in Ubuntu:
  New

Bug description:
  Hi, the following program gets a segmentation fault. It works OK on
  another machine (g++ (GCC) 4.1.2 20080704 (Red Hat 4.1.2-52)).

  #include <iostream>
  #include <string>
  #include <stdexcept>

  using namespace std;

  class A {
  public:
    // Singleton
    static A & instance();

  private:
    A() {
  	throw std::runtime_error("throw\n");
    }

  };

  A & A::instance() {
    static A inst;
    return inst;
  }

  int main () {

    const A & a = A::instance();

    return 0;
  }

  % g++ -o foo foo.cc
  % ./foo
  terminate called after throwing an instance of 'std::runtime_error'
    what():  throw

  Aborted (core dumped)
