IO.syncStep leads to double execution #2858
Description
Hey guys,
I found which seems to me a critical bug during migration of codebase from ce2 to ce3
The code below prints hello twice, I would expect hello to be printed once.
IO
.apply { println("hello") }
.flatMap { _ => IO.cede }
.as(Succeeded)
.syncStep
.unsafeRunSync() match {
case Right(a) => Future.successful(a)
case Left(a) => a.unsafeToFuture()
}
