simplifyLog(2*sqrt(2)*log(2))

(1)

It's perhaps the line for i in 1..#terms repeat in manip.spad file and simplifyLog1 function to change in for i in #term..1 by -1 repeat because there is a delete!(terms,i) in the loop.

It's perhaps necessary to add exprs := reverse! exprs at the end of the loop, if we want to remain the order of the terms.
