Cannot call an inline method that references a field from an anonymous class created with a transparent inline extension in 3.2.0

[arainko]

Compiler version

3.2.0, 3.2.2-RC1-bin-20220909-eaa2889-NIGHTLY

Minimized code

package repro

// this needs to be in a separate file, if placed in the same file then everything works
extension (src: String) {

  // a new anonymous class is essential, it works as expected if this is just a constructor call
  transparent inline def intoViaRepro = new TestClass(src) {} 
}

package repro

class TestClass(source: String) {
  inline def access = source
}

object Repro {
  private val value = "whatever"
  value.intoViaRepro.access
}

Output

[info] exception occurred while compiling ducktape/repro/src/main/scala/Repro.scala, ducktape/repro/src/main/scala/syntax.scala
java.lang.AssertionError: assertion failed: private value value in object Repro in ducktape/repro/src/main/scala/Repro.scala accessed from constructor $anon in ducktape/repro/src/main/scala/syntax.scala while compiling ducktape/repro/src/main/scala/Repro.scala, ducktape/repro/src/main/scala/syntax.scala

Expectation

The code compiles as it did in 3.1.3.

This can be worked around by doing this:

object Repro {
  private val value = "whatever"

  private def workaround(value: String) =
    value.intoViaRepro.access

  workaround(value)
}

Context

I've stumbled upon this error when compiling ducktape with Scala 3.2.0, the file that fails is located here, the class which needs a new anonymus instance here and the extension definition here.
