I am encountering this bug too in oracular, and it is breaking a lot of my scripts. A workaround is to use /usr/bin/printf instead of the bash builtin until this is fixed. I do not understand why the Debian folks reverted the severity from critical to normal as this is breaking external programs. Moving severity to critical.
