In July 2006, gnulib changed the dirname module so that base_name started returning a malloc'd result, for similarity with dir_name, and added last_component as the replacement that did not malloc.

That means the following constructs in CVS head now leak memory (and similar constructs are on the 4.2.x branch), since 4.2.28 and 4.3.1:

./find/find.c:  char *base = base_name(pathname);
./find/pred.c:   checked_print_quoted (dest, segment->text, base_name (pathname));
./find/pred.c:  base = base_name (pathname);
./find/pred.c:  base = base_name (pathname);
./locate/locate.c:  procdata->munged_filename = base_name(procdata->original_filename);

They should either free the memory, or use s/base_name/last_component/.
