Segmentation fault (core dumped)
function byte_snprintf() when calculating SUM, where SUM is in terabyte,
we go past the kLabel_Byte/kLabel_bit array limit (by increment of conv
past kConv_Giga) and this causes iperf to segfault because suffix is
pointing past the array bounds.
A fix for this issue is available in:
