  No... the master branch relies on talloc() and other methods to avoid
this issue.

  The problem was that the rlm_eap code expects that the type-specific
data is the parsed config file data.  The rlm_eap_tls module instead
buried it inside of another pointer.  So... the config file free code
was treating structure type A as a structure of type B.  And boom.

  I've pushed an ugly but simple fix.  It should now work.
