Re: make 3.79: core dump expanding target specific variables

This has been fixed in CVS (it just gives "[2]" again).

`current_variable_set_list->next != 0' failed.
  rb>   Aborted (core dumped)
  rb>   $

This core dump has been fixed, too.

Unfortunately, now it prints this:

  "[hello hello]"

which is also wrong :(.  I'll look at it.
