Indeed - triggers a latent bug in ARC gcc !

Yeah there's a 4.8.5 based one (referred to as GNU 2016.03) - will prebuilt
toolchain suffice or would you prefer building on your own. Prebuilt could be
found below.
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2016.03
For building on your own, Alexey can point to upstream buildroot which enabled
2016.03 tools.
Thx,
