Let me refresh your memory. You've seen this deadlock before:

  Thread 1                    Thread 2
  dlopen                      malloc
   ... takes loader lock       ... takes malloc lock
   malloc                      _Unwind_Backtrace
   ... needs malloc lock         dl_iterate_phdr
       held by T2                ... needs loader lock held by T1
