/* The purpose of this test is to exercise the code in elf/dl-loac.c
   (_dl_init_paths) or thereabout and ensure that static binaries
   don't crash when expanding DSTs.

   If the dynamic loader code linked into the static binary cannot
   handle expanding the DSTs e.g. null-deref on an incomplete link
   map, then it will crash before reaching main, so the test harness
   is unnecessary.  */
