String interpolation parsing in initializers regression in 3.2.0

[jrudolph]

Compiler version

3.2.0

Minimized code

val str = "test"
class Test { s"$str" }

Output

-- Error: ----------------------------------------------------------------------
2 |class Test { s"$str" }
  |                   ^
  |                   unclosed string literal

Expectation

Compiles as in 3.1.x.

This seems to be a particular issue about initializers. Here are a few instances that work:

{ val str = "test"; s"$str" }
class Test(str: String) { def test = s"$str" }
{ val str = "test"; trait Test { s"${str}" } }

Seems to be fixed in 3.2.1-RC1 so just filing for reference. Maybe same/similar cause as #15514?

Yes, that is the same issue. The shared element is the string interpolation in "self-type" position of a template.
