Yes. As you can see in the manual[1], "The blocks in the list of data 
blocks must be contiguous and non-overlapping".

If ddrescue has produced the logfile above, then it is a bug. Ddrescue 
would not accept such logfile as input.

Inserting the missing area as a non-tried block and restarting (maybe 
using ddrescue 1.19) will probably solve the problem, but I am very 
interested in knowing the cause of the missing area.
