2.13.0-M3 compiler crash with "Synthetic tree ... contains nonsynthetic tree" #10706
Description
same message as #8510 , #10095 .
but scalaz 7.3 does not use macros and another versions(Scala 2.11.12, 2.12.4) builds fine
- Resolve ambiguous implicits for Scala 2.13.0-M3 scalaz/scalaz#1632
- https://travis-ci.org/scalaz/scalaz/jobs/336427349
how to reproduce
git clone -b ambig-implicit https://github.com/xuwei-k/scalaz.git
cd scalaz
sbt '++ 2.13.0-M3!' rootJVM/test:compile
