Is there a public git tree to get the code you do build?

Or, is it possible to list the last several commits of file lib/maple_tree.c
so that I can reproduce it on my side.

I guess maybe I can try to reproduce this with:

   * set CONFIG_FRAM_WARN to 1024
   * set KCFLAGS="-O3"

I would try to take a look first.

Is the GCC version matters? I don't have the exact version at hand. Have you
tried other version?
