Details:

Since 2009, GDB is able to "record the execution of a program being debugged
by gdb, and then 'play back' the recorded execution, deterministicly and
repeatedly if desired." [1]

    1. https://sourceware.org/gdb/wiki/ProcessRecord

It is already possible to use those features in the gdb console in DDD, but DD
will not update its source code window when using various reverse-* commands,
only the forward ones that it already knows.

That is, if I do reverse-continue or reverse-step, the line showed in the code
window will not move (but the display window will update variables).
