error: fatal error (server aborted): key not found: value C
three errors found
 ~/code/scratch:

If C is a case class without constructor default params, the name clash is reported without a crash:

 ~/code/scratch: scala -e 'object T { case class C(); val C = 0 } '
/var/folders/QM/QM9Dr+BMFvCtrP8ulVgcNE+++TI/-Tmp-/scalacmd110122063062379165.scala:1: error: C is already defined as (compiler-generated) case class companion object C
object T { case class C(); val C = 0 } 
                               ^
one error found

Tested both in the REPL behaviour and with scalac.

Seem like a regression to me ( please update to the latest, latest since in r24005 I removed code that was causing infinite loop in this):
