Fatal signal 11 (SIGSEGV), code 1, fault addr 0x10 in tid 20710 - on LG G5

      We seem to keep getting regular crashes on one of our test devices. Either when calling

          try (Realm realm = Realm.getDefaultInstance()) {
              if (!realm.isInTransaction()) {
                  realm.beginTransaction();
              }
              //do things here
          }
      

      we'll get the app never getting past the "begin transaction" line, or sometimes it'll throw the following stack.

      It doesn't seem to happen on other devices other than this one.
