When I try the merge-2.067 branch it fails even earlier.

That's an issue in DDMD. LDC does not offer y2lx in core.math because it makes no sense on platforms beyond x86 (and we would have to implement it using inline asm anyway). We could add an inline asm version to our runtime, but I'd rather our frontend did not rely on a platform-specific operation with wonky semantics.

I agree to these semtiments about y2lx(p1). I have no idea who or why someone thought it was considered a good idea to add it to CTFE in the first place.
