class B extends {

  val v = "foo"

} with A


... gives the following error:

I don't know what's specific about scaladoc - scalac works fine - but I assigned it Martin because there's nothing scaladoc-ish in the stack trace

Crashes the presentation compiler but does not crash the build compiler. That would explain why ScalaDoc is affected, as it runs in the onlyPresentation mode. Could this occur because not all the phases are being run?

Just updated to the new trunk and it doesn't seem to crash anymore. Already fixed.

Users are complaining that they bug is not fixed. Strange, I'll look into it.

I compiled in the presentation compiler but did not see a crash. Reassigned to Sean. -- Martin
