           Summary: alias this declaration and unknown identifiers lead to
                    segmentation fault
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: tvwhite51 gmail.com



If two classes alias this each other and their is an unknown identifier DMD
will fail with segmentation fault: 11. This is on DMD 2.061, Mac OS X 10.8.2.

Example:

class foo {
    bar fun;
    alias fun this;

    this() {
        fun = new bar(this);
        fun.a = 5; //remove this line and the program will compile.
    }
}

class bar {
    foo sun;
    alias sun this;

    this(foo t) {
        sun = t;
    }
}

void main() {
    foo fun = new foo;
}
