In CTFE, an array of NaN will not be equal to itself. However, this return
'true' in the runtime:

-----------------------------------------------
bool f() {
    float[] h = [float.nan];
    float[] i = [float.nan];
    return h == i;
}
void main() {
    static assert(!f());    // ctfe is OK
    assert(!f());           // runtime asserts
}
-----------------------------------------------

The CTFE and runtime result should be consistent.
