sum([1e+308, 1e+308, 1e-308]) raises an OverflowError due to the
overflow of the first partial sum.

+ Note 3: The intermediate values lo, yr, and hi are declared volatile so
aggressive compilers won't algebraicly reduce lo to always be exactly 0.0.
Also, the volatile declaration forces the values to be stored in memory as
regular doubles instead of extended long precision (80-bit) values. This

+ prevents double rounding because any addition or subtraction of two doubles
can be resolved exactly into double-sized hi and lo values. As long as the
hi value gets forced into a double before yr and lo are computed, the extra
bits in downstream extended precision operations (x87 for example) will be
