[Bug other/36030] Throwing exceptions in multiple threads leads to spinning in call to _Unwind_Find_FDE

This is a bug in your glibc.  Current glibc has

__dl_iterate_phdr (int (*callback) (struct dl_phdr_info *info,
                                    size_t size, void *data), void *data)
{
  struct link_map *l;
  struct dl_phdr_info info;
  int ret = 0;

  /* Make sure we are alone.  */
  __rtld_lock_lock_recursive (GL(dl_load_lock));
  __libc_cleanup_push (cancel_handler, 0);
...

so it is already properly locked.

Which glibc version do you use?  You should probably report this as a bug
to your vendor.
