Tested with dmd 0.91, win2k and win98se.

The attached files compile to an executable that produces the desired output but crashes after the main() function has finished.

I haven't been able to reproduce the bug with a smaller example, sorry.

The problem seems to be the import statement inside class A combined with the six integer variables (strange, there has to be six of them, not five, nor seven).

Other than that I can tell you much about it.

I'm sorry, that should be "Crash".

Does this happen in both console and window (ie, no console) mode? My stuff has this problem, but I figured I was just doing something stupid because the winsamp sample worked fine.

Either way. I was chasing another bug on a windows program that make a method almost *disappear* after linking but found this instead.

Just to let you know that this bug is still present in dmd 0.94. ;)

You're right. (More comments belows...)

/* *** a.d *** */

module a;

class A
{
    import b;

    this()
    {
        printf("A.this()\n");
        _b1 = null;
    }
private:
    int _i1, _i2, _i3, _i4, _i5, _i6;

    //import b;
    B _b1;
}


/* *** b.d *** */

module b;

private import a;

class B : A
{
public:
    this()
    {
        printf("B.this(B)\n");
        super();
    }
}

I don't really know anything about the bug, but I'm surprised that class A can contain a member of class B (that inherits from A). Seems like a case of which came first, the chicken or the egg?

But it does compiles and even runs if there aren't six integers. So, classes much be able to contain objects of an inherited class. I didn't even think that'd be possible. D keeps on getting cooler.

By the way, this seems to be another way to avoid the runtime error:

private:
    //import b;
    B _b1;   /* moved above the 6 integers */

    int _i1, _i2, _i3, _i4, _i5, _i6;
}




/* *** *** Other files for reference... *** *** */

/* *** build.bat *** */

@dmd main.d a.d b.d imp.d
main.exe
pause



/* *** main.d *** */

import imp;

void main()
{
    printf("main() {\n");
    B b1 = new B();
    printf("}\n");
}



/* *** imp.d *** */

module imp;

import a;
import b;

Try running it under a debugger and see where it is failing. Do you have destructors?
