Hi scala-users,

I've managed to make the compiler crash again! Unfortunately the code
that causes it is part of a large project, and so far I've failed to
create a minimal example of the problem. I've run the compiler with
"-verbose -Ylog:icode -Ydebug". The stack trace at the crash is
immediately below, and the entire compiler output appears at the end
of this email.

If anyone has a guess as to what's causing this, maybe that will help
me find a minimal example, so I can create an issue.

best regards,
Scott Morrison

(ps -- is this is preferred mailing list for this?)

Ah, I found a minimal example, and have created an issue at
.
