I just marked this as affecting me as well. However, I had to add one
other step to reproduce the bug using the instructions above. As the bug
title says, the problem only happens when the working directory (not
necessarily the one on which find is being run) is unreadable or not
executable by the current user. So, I had to add "chmod u-r ./2" before
the line "cd 2". The find command then fails with

find: pred.c:1932: launch: Assertion `starting_desc >= 0' failed.
Aborted (core dumped)

As a real-world example of this bug, this can happen when you are
logged-in as root, and in /root and "su" to another user. You are
therefore left in /root but without having read/execute permissions to
it. find with -exec therefore fails, even if you are searching another
directory. This came up while using Puppet, which included a 'find'
command. Of course, switching to another directory solved the problem.
