  This error is being produced by the regular expression library on your
system.  FreeRADIUS is just asking the library to use the regular
expression... and it says no.

  The "users" file parser was changed in 2.1.x, but that was only to
deal with back-slashed.  It shouldn't be affecting this.

  Try using "unlang", as suggested elsewhere.
