Comment 1 Aleksander 2016-10-08 04:20:59 UTC 
Ooops.
Now it fails to build event with gcc with same error.

I setup llvm/clang as system compiler and try to rebuild system:
emerge -e system
Comment 2 Aleksander 2016-10-08 04:25:42 UTC 
Problem that libmnl build with clang.
If i rebuild it with gcc, iproute2 builds fine even with llvm/clang
Comment 3 Aleksander 2016-10-08 04:28:42 UTC 
Problem with stable libmnl from portage(1.0.3-r1)
If i unmask 1.0.4 everything builds fine with LLVM/CLANG

Sorry for all this flood.

if it's fixed already with 1.0.4, then there's nothing to do here

for new experimental work, we rarely care about the state of the stable tree.  make sure things are working in unstable, and eventually that state converges into the stable tree.
