Bug 13182

Sometimes I met the following failure.

Inconsistency detected by ld.so: dl-open.c: 274: dl_open_worker: Assertion `_dl_debug_initialize (0, args->nsid)->r_state == RT_CONSISTENT' failed!

The key error message is this dl-open.c assertion failure.

Please see some additional information here. Hope it would be helpful.
I googled and found the following commit in glibc:
commit ccdb048df457d581f6ac7ede8b0c7a593a891dfa

    Fix recursive dlopen.
    
    The ability to recursively call dlopen is useful for malloc
    implementations that wish to load other dynamic modules that
    implement reentrant/AS-safe functions to use in their own
    implementation.
    
    Given that a user malloc implementation may be called by an
    ongoing dlopen to allocate memory the user malloc
    implementation interrupts dlopen and if it calls dlopen again
    that's a reentrant call.
    
    This patch fixes the issues with the ld.so.cache mapping
    and the _r_debug assertion which prevent this from working
    as expected.
    
    See:
    https://sourceware.org/ml/libc-alpha/2014-12/msg00446.html

The commit seems related. But our glibc has included this commit. And we are using glibc from uninative-tarball.

The current glibc's codes still have a _dl_debug_initialize assertion in dl_open_worker.
  /* It was already open.  */
  if (__glibc_unlikely (new->l_searchlist.r_list != NULL))
    {
      /* Let the user know about the opencount.  */
      if (__glibc_unlikely (GLRO(dl_debug_mask) & DL_DEBUG_FILES))
        _dl_debug_printf ("opening file=%s [%lu]; direct_opencount=%u\n\n",
                          new->l_name, new->l_ns, new->l_direct_opencount);

      /* If the user requested the object to be in the global namespace
         but it is not so far, add it now.  */
      if ((mode & RTLD_GLOBAL) && new->l_global == 0)
        (void) add_to_global (new);

      assert (_dl_debug_initialize (0, args->nsid)->r_state == RT_CONSISTENT);

      return;
    }
