Seems to have been indirectly caused by the stabilization of std::iter::Iterator::flatten (rust-lang/rust#51511) and by using an outdated version of ethcore in this repo.

It has already been fixed in parity-ethereum here: openethereum/parity-ethereum#8606

@phansch Seems there was no backport for 1.11.11 for this fix 😂

I have reverted my RUST version to 1.26.00 and it was compiling. Thanks
