- deallocate all our data structures on exit (to help find memory leaks, bad pointers, and general logic errors) - fixed memory leak when allocating pad names in instantiation - added "magic" environment variable FPED_NO_GUI to run fped without initializing Gtk+ - added valgrind wrapper "leakcheck" - delete.c: destroy() now requires a deletion to exist - vacate_op: free string expressions - destroy_obj: free measurement labels - delete_references: use do_delete_obj so the we don't bump the group number - delete_frame: delete references after deleting the frame itself, so they end up on the stack above the frame and get destroyed first - do_delete_vec: like above, even though it doesn't matter here git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5506 99fdad57-331a-0410-800a-d7fa5415bdb3
