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.
