        <pre>The code at the bottom compiled with Xcode or clang++ command line crashes in 

template <class _NodePtr>
inline _LIBCPP_INLINE_VISIBILITY
bool
__tree_is_left_child(_NodePtr __x) _NOEXCEPT
{
    return __x == __x->__parent_->__left_;
}

with EXC_BAD_ACCESS.


In contrast if I use the g++ compiler at
<a href="http://www.tutorialspoint.com/compile_cpp11_online.php">http://www.tutorialspoint.com/compile_cpp11_online.php</a> it works just fine.

CODE:


#include <iostream>
#include <set>

struct blabla
{
public:
    int _x, _y;
    blabla() : _x(1), _y(2) {}

    void print()
    {
        std::cout<<_x<<":"<<_y<<std::endl;
    }
};


int main(int argc, const char * argv[]) {
    // insert code here...
    std::cout << "Hello, World!\n";

    std::set<blabla *> blablaset;
    for(int i=0; i<10; i++)
    {
        blablaset.insert(new blabla());
    }

    for(auto b : blablaset)
    {
        //b->print();
        auto found = blablaset.find(b);
        if(found != blablaset.end())
        {
            std::cout<<"found "<<b<<". deleting."<<std::endl;
            blablaset.erase(found);
            delete b;
        }
    }

    return 0;
}
