Yes, this is a known bug that has been fixed a while ago. I guess
it is time to release 6.15.01:

  5. cd - twice from a directory that contained a glob pattern,
     expands the glob twice (Mark Santcroos)
  4. MidnightBsd support (Lucas Holt)
  3. Fix history substitution core-dump with no history entries
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2. Merge two character tables that are the same (Martin Kraemer)
  1. On ancient 7 bit locales, punctuation characters are used to
     denote special characters such as umlaut, adiaresis, etc.
     These characters return true for isalpha/isalnum. Ignore them
     because they break parsing (Martin Kraemer)
