[ksh93] defunct 'fc' command?

In a recent thread about an emacs mode editing mode function in ksh
there was a note about ^O ("it will stay in the history and move to
the next line"). Thinking about an emulation in vi editing mode I
noticed that 'fc' doesn't seem to work on my Limux platform (neither
with ksh93u+ nor with ksh93u+m). Usually I use that built-in command
only as 'fc -l' (to list the history entries), and omitting the '-l'
should execute these commands. Alas, 'fc <from> <to>' doesn't work;
for example

$ fc -l 1013 1015
1013 ls X
1014 ls Y
1015 ls Z
$ fc 1013 1015
15
^C
?
^Z[1] + Stopped                  fc 1013 1015
$ kill %%
[1] + Terminated               fc 1013 1015


Is that an issue in my environment (or on my platform), or a bug?
