Example code causing ICE
The attached file crashes clang++-8.0.0, and trunk (367966).
The crashes are on the lines with a comment '// E'. If those lines are
commented out, it compiles.
There are two ways to make it compile. Remove '= std::move(function)' under the
comment '// 1' or remove the forwarding reference '&&' under the comment '// 2'
