           Summary: dmd crash: "Internal error: ..\ztc\cod4.c 357"
           Product: D
           Version: 1.020
          Platform: PC

        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

following code crashes the compiler while compiling with -O for optimization.

[CODE]
struct C {

    C copy() {

        C cpy;

        return cpy;
    }
}

void foo(C _c) {

    foo( _c.copy() );
}

void main() {

    C c;

    foo(c);
}
[/CODE]

crashes at least with dmd1.020 and dmd2.003.

compile call: "dmd -c -O main.d"
output: "Internal error: ..\ztc\cod4.c 357"

PS: i know this code is producing a stack overflow on runtime but thats not the
bug ;). i cant get in runtime when the compiler crashes.
