This D2 program:
double[7_000_000] array = void;
void main() {}
DMD 2.055 gives an expected error message:
test.d(1): Error: index 7000000 overflow for static array
But this similar program:
struct Foo {
double x /*= 0*/;
}
Foo[7_000_000] array = void;
void main() {}
Causes a crash of optlink at EIP=004114FC.

Apart from the linker crash this could also be a DMD accepts-invalid bug.

Now causes:
test.d(4): Error: variable test.array size of 0x3567e00 exceeds max allowed size 0x1000000
