I now understand the problem.  Thanks.

Yes, I see.  (I was wrong.)

https://bugs.debian.org/727621
There seems to be some issue related to ATOMIC_type_LOCK_FREE.  (I have
no clue but it is related to type.)

I also see FEDORA applied attached arm patch changing float to double
and doing the alignment computing for mapped file.

Is this patch something which work around the issue on armel?

Also, as I see the upstream git repo, just after his release of this
tar, he is commiting 
     5c274357ceaaff941b91e12d3f2f4714df0ecd16
to revert CMakeLists.txt of oldscheool branch as:

-if(UNIX)
-  add_definitions("-std=c++11")
-endif(UNIX)

Then recent commit has
+ if(NOT BOOST_USE_CXX11)
+   add_definitions("-DBOOST_NO_CXX11_SCOPED_ENUMS")
+ endif()

Are these kind of updates needed?

Guo Yixuan,

Can you talk to the upstream on this issue and what oldschool devel
branches mean?
