struct HasUnion { union { int a, b; } } void main() { auto x = new HasUnion(); } This segfaults when trying to optimize `new HasUnion()`, which has been expanded to `new HasUnion(0, )` with the second argument being NULL in the ast.

Ah, my bad! I noticed my Digger cache got messed up today, sorry about that.
