Question about calling D method from C/C++

[Eric]

If I use "new" inside a D method that is called from a c++ program
it causes a segmentation fault.  For example:

C++ code:

#include "dcode.h"

int main(int argc, char *argv[]) {
    hello();
    return(0);
}

D code:

class X {
    private int x;
    this() { x = 5; }
    public int getX() { return(x); }
}

extern (C++) void hello() {
    X x = new X();
}

This will crash when the line "X x = new X()" is executed.
Is this to be expected?
