assertion failed: missing outer accessor

[OndrejSpanel]

Compiler version

3.6.3

Minimized code

I was not able to to minimize the code yet. However, this is what triggers the error:

Crashes:

class Assembly(val content: GeometryContent, val matContent: MaterialContent, val explicitName: Option[Name], val defBBox: Option[Box3D] = None) extends HasEquivalent[Assembly] {

Does not crash

class Assembly(val content: GeometryContent, val matContent: MaterialContent, val explicitName: Option[Name], val defBBox: Option[String] = None) extends HasEquivalent[Assembly] {

While checking which compiler version is affected, I got two different crashes got mixed up. The callstack reported originally in the first post is caused by #22727. The one belonging to this issue is:

     while compiling: C:\Dev\tempi\threeJVM\src\main\scala\net\gamatron\procas\curve\CurveEditFrame.scala
