Damn, sum(lens) on the line above can be negative, which throws an ErrorException instead of the expected ArgumentError. Should we add a check like this?
n = sum(lens)
n >= 0 || throw(ArgumentError("lengths must be non-negative"))Otherwise, let's go back to the previous version.

Added a check on the sum per your suggestion since we need to compute the sum anyway in order to initialize the output array.
