The following code consistently fails to compile with -O2 or -O3. I've reduced
the case as far as possible.

Output:

1.    <eof> parser at end of file
2.    Code generation
3.    Running pass 'X86 DAG->DAG Instruction Selection' on function
'@_ZN4TestC2Ev'


#include <boost/shared_ptr.hpp>
#include <deque>

namespace {
    struct A { };
}

struct Test
{
    Test();
    std::deque<boost::shared_ptr<A> > x;
};

Test::Test() {}
