I am engaged in the modernization of a large project to 2.10.4 to 2.11.4. Did I get a compiler crash anyway to display the name of the source file causing the crash? I can get the full track with "last everitt / compile: compile"
I am going to return to erasing large chunks of the project into a binary search for the cause of the failure.
Here is the btw trace:

Edit: after erasing and commenting on a large number of files, I simplified this:
case class A(x: String) case class B(a: A, y: String) class C(var b: B) { def a = ba b.copy(a = a.copy()) }
Edit2: Best of all, I can say that there is no good choice for this, I'm going to move on, I filed an error message for this problem ( SI-9035 ). If anyone knows an option / way to do this, write an answer! In the meantime, I will just continue to use the method that I have used since version 2.6: delete files and comment out lines until I get to the minimum example and publish an error report. Thanks for the ideas.
