Comment 2 Siteshwar Vashisht 2017-01-20 09:15:51 EST

This has been fixed in bash-4.4 and works as expected in rawhide.

Comment 3 Pavel Raiskup 2017-01-20 09:43:48 EST

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.
