Looks like a bug in Clang to me, although working around it is fine, but it's not my call.
Nevertheless I think you should report it to Clang so they fix it.
Why do you think that it's a clang bug? Using fldl + fstpl to store and fetch the double to/from the floating point stack is perfectly legitimate.
Well, because jsval_t is a union, not a double. Shouldn't assignment be a bitwise copy? The compiler can't know what actual type is used by the union here. Unless I misremember the C standard.
