I expect that this is the same as https://bugs.kde.org/show_bug.cgi?id=432804 which is fixed in https://invent.kde.org/utilities/konsole/-/commit/96a18a9b7f651e27da99f8b483d84fdb9a1a1e62

But in fact, I cannot reproduce this bug. The printf does not hang konsole, though it does not print kde, as it does with the patch.

Whether it hangs depends on the shell used and shell configuration. On ksh you may need to type ESC + \ to unhang konsole. bash invoked as sh seems to hang harder: I've not found a way to unhang it.
