Comment 2 Siteshwar Vashisht 2017-01-20 14:15:51 UTC 
This has been fixed in bash-4.4 and works as expected in rawhide.
Comment 3 Pavel Raiskup 2017-01-20 14:43:48 UTC 
Sorry for the wrong reproducer, because it is not obvious what I tried to
say.  So just FTR:

Please don't use the '$ bash -c CMD' command, but rather real interactive
session by '$ bash'.  Then hit the 'CMD' into the started interactive shell,
and try to 'ctrl^C' it.  You'll see the shell is also interrupted.
