2259 – Assertion failure: '0' on line 122 in file 'statement.c'

The DMD compiler crashes when I compile the code below (using DMD v1.033, Windows XP). The compiler do identify the first error:
main.d(8): Error: foreach: void is not an aggregate type
but then I get an assertion failure:
Assertion failure: '0' on line 122 in file 'statement.c'
This is perhaps a strange error and I don't know if anyone else have seen it. I do get the error even though I don't use the -debug flag. The error doesn't occur if I remove the "debug Object foo"-line.
module main;
public void bar() {
	
}
void main() {
	foreach(Object o ; bar()){
		debug Object foo = null; //error
	}
}
