While testing simple_prompt() revisions, I happened to notice that current initdb behaves rather badly when --pwprompt is specified and the user miskeys the second password. It complains about the mismatch, does "rm -rf" on the data directory, and exits. The problem is that since commit c4a8812cf, there's a standalone backend sitting waiting for commands at that point. It gets unhappy about its datadir having gone away, and spews a PANIC message at the user, which is not nice. (And the shell then adds to the mess with meaningless bleating about a core dump...) We don't really want that sort of thing to happen unless there's an internal failure in initdb, which this surely is not. The best fix seems to be to move the collection of the password earlier, so that it's done essentially as part of argument collection, rather than at the rather ad-hoc time it was done before. Back-patch to 9.6 where the problem was introduced.
