scalbln takes a "long" second argument, which on x86_64 is a signed 64-bit
value. When that is 4294966274, a large positive value, a result of -inf as
reported here is the correct result. If you pass (int)4294966274, a negative
value, then you do get -0X0.5555555555556P-1022 as expected. So there is no
bug here.
