>Description:
After checking out the 6-1 tag, I was cross-compiling for evbarm with the following overall command.

./build.sh -O ../obj -T ../tools -U -m evbarm distribution

Eventually the build dies inside src/external/bsd/atf/dist/atf-c++/detail.  This always reproduces.

 I assume you are using clang as the host compiler? I wonder if it is the
 same issue with tree.c that is hacked around with -O0 in-tree.
