Position not set error for `SourceFile` annotation, when accessed from a `transparent` macro

[vigoo]

Compiler version

3.2.1

Minimized code

The following repository contains a minimized reproducer: https://github.com/vigoo/scala3-annotation-bug

Below I'm summarizing it but for the crash it is important to have two separate compiled modules.

Let's define a custom annotation and a case class that uses it:

import scala.annotation.StaticAnnotation

final case class testAnnotation(steps: String) extends StaticAnnotation

@testAnnotation("x")
final case class Record(a: String, b: Int)

then we create a macro that tries to collect all annotations of a given type:

case class Schema(annotations: List[Any])

object DeriveSchema {
  transparent inline def gen[T]: Schema = ${ deriveSchema[T] }

  def deriveSchema[T: Type](using ctx: Quotes): Expr[Schema] = {
    import ctx.reflect._

    val typeRepr = TypeRepr.of[T]
    val annotationExprs = TypeRepr.of[T].typeSymbol.annotations.map(_.asExpr)
//    val annotations = '{List.empty}
    val annotations = '{List(${Expr.ofSeq(annotationExprs)})} // NOTE: if this line is just an empty list it does not crash

    '{Schema($annotations)}
  }
}

and call it:

@main def run() = {
  val schema: Schema = DeriveSchema.gen[Record]
  println(schema)
}

if Record is defined in a different compilation unit (a separate sbt subproject in the linked repo) the compiler crashes. If Record is defined next to the macro invocation it works. Also if the val annotations = line is replaced to the commented out one, it does not crash.

Minimized version:

// _1.scala
import scala.quoted.*

final case class Record(a: String, b: Int)

transparent inline def anns[T]: List[Any] = ${ annsImpl[T] }

def annsImpl[T: Type](using ctx: Quotes): Expr[List[Any]] = {
  import ctx.reflect.*

  val typeRepr = TypeRepr.of[T]
  val annotationExprs = TypeRepr.of[T].typeSymbol.annotations.map(_.asExpr)
  val annotations = Expr.ofList(annotationExprs)

  annotations
}

// _2.scala
def Test =
  val a = anns[Record]

An important note is that the compiler only crashes if the macro is transparent.

It looks like we do not set positions for the trees of synthesized annotations such as SourceFile. We should have a position for all those trees. To start, we should make Ycheck find annotations without positions.
