FYI I've just pushed this branch,
https://github.com/milessabin/shapeless/tree/topic/2.12.0-RC1-regression-2
This is shapeless at the commit that's supposed to be checked by the
community build,
https://github.com/scala/community-builds/blob/2.12.x/common.conf#L71
Plus the delta to the build to get it to build with RC1 (actually
Adriaan's update to that),
https://github.com/milessabin/shapeless/commit/a205e21805f7039bfb6ae3bdd7980eca0ee0a0ca
It also exhibits the crash, so it's pretty clear that the community
build can't be compiling the shapeless tests.
Cheers,
Miles
