Dear Scalararians,
We're seeing a compiler crash. If we include this file anywhere in our project -- even in a separate package -- the compiler crashes. If i make a separate project with just this file, that project compiles.
i've spent about as much time as i've got to make a minimal repro. i've put it in the scalaCompilerErrorRepro branch of SpecialK. Since i don't have a more self-contained repro case i haven't opened a ticket.
Any help would be greatly appreciated.
Love,
--greg

P.S. The contents of the crash-inducing file are simply

P.P.S. We rev'ed the compiler to 2.10.2 and still got the same error. It's much worse because the error report describes problems in completely unrelated files that have been compiling for years and ported without complaint to the 2.10 version. However, if we refactor the code as below, pulling the stack trace to string conversion to a separate method then the compiler doesn't crash.
package com.biosimilarity.lift.model.store.scribble
import scala.util.continuations._
trait Scribble[Resource] {
def stackTraceToString( t : Throwable ) : String = {
val errors : java.io.StringWriter = new java.io.StringWriter()
t.printStackTrace( new java.io.PrintWriter( errors ) )
errors.toString( )
}

sk : Option[Resource] => Unit @suspendable
) : Option[Resource] => Unit @suspendable = {

Hi Greg,
That was the last tree through the typechecker. This crash comes much later, so it is not pertinent information. We've got a fix in the pipeline for the crash diagnostic for 2.11.
However, if we refactor the code as below, pulling the stack trace to string conversion to a separate method then the compiler doesn't crash.
Glad you've found a workaround.
First of all, a heads up regarding CPS: We don't have resources assigned for maintenance of the CPS compiler plugin. In fact, we're thinking of declaring it deprecated. It has some architectural issues (most notably: intimate relationship with typechecking under the annotation-driven pluggable subtyping logic) that means it has a long tail of hard- or impossible-to-fix bugs and limitations.
Our vision is to provide a more focussed version of CPS as scala-async, which is implemented with def-macros. It provides a DSL for working with Futures (or other Future-like APIs). Admittedly, this is far less general, but that does have the benefit of eliminating the cryptic type errors which folks often to hit with @cps.
But please do report the bug if you can tease it down a standalone test. I can't find an existing ticket that fits this. Its a regression, and while I'm assuming it is related to CPS that might not be the case.

I would plead that this plugin not be deprecated if at all possible, our project is entirely dependant on it, and I think Greg's is too. Moreover, there are very few programming languages that support continuations, and even fewer that support portable continuations.
While portable continuations might seem to be an esoteric feature, in actuality they are extremely relevant to many of the real-world challenges that programmers face today, in particular the problem of building scalable distributed and fault tolerant software. In my humble opinion, portable continuations are our best chance of achieving the holy grail of allowing software to be written that can be scaled across tens, hundreds, or maybe even thousands of computers - just as easily as writing software to run on a single CPU. The existence of the continuations plugin was what convinced me to base our project on Scala.
Typically, useful functionality is only deprecated in an API when there is a better alternative. Deprecating the continuations plugin in favor of an unspecified Futures-based system may seriously screw quite a few people who made quite early bets on Scala. I hope you take that into consideration in your decision to deprecate it.
Ian.
