Hi.

dmd freezes if the module name is used as a class name under a certain
condition.
The condition is as follows.

* compile OK ****
* a0.d ***********
import b0;

void main() {
b0 r;
}
* b0.d ***********
import a0;
class b0{}
*****************
>dmd a0.d b0.d        ... OK

* freeze 1 ******
* a1.d **********
import b1;

void main() {
b1 r;
}
* b1.d **********
import a1;
class B1{}
*****************

>dmd a1.d b1.c   ... freeze

* freeze 2 ******
* a2.d **********
import b2;

void main() {
b2 r;
}
* b2.d **********
import a2;
*****************

>dmd a2.d b2.d   ... freeze
>dmd -c a2.d     ... freeze
>dmd -c b2.d     ... ok

* compile error *
* a3.d **********
import b3;

void main() {
b3 r;
b4 r2;
}
* b3.d (empty)***
*****************

>dmd a3.d b3.d    ... compile error
a3.d(4): import a3.b3 is used as a type
a3.d(4): variable a3.main.r voids have no value
a3.d(5): identifier 'b4' is not defined
a3.d(5): b4 is used as a type
a3.d(5): variable a3.main.r2 voids have no value
