Bug tracker housekeeping, a new crasher, low-hanging-fruit for 2.9

Hi everyone,

I made small list of tickets which might be fixable with small/without impact for Scala 2.9 or which changed greatly in behavior compared to earlier versions:


Runtime errors which became a compiler crash recently:

#2d2d2d  Multiple assignment does not do correct typing
https://lampsvn.epfl.ch/trac/scala/ticket/140

#6f6f6f  Bug in structural types/refinements allows singleton property to be violated
https://lampsvn.epfl.ch/trac/scala/ticket/963


Low-hanging fruits (with patches):

#2196 Use java.lang.Long.bitCount in BitSetFactory
https://lampsvn.epfl.ch/trac/scala/ticket/2196

#4520 OutOfMemoryErrors and inifinte loops in scala.xml.parsing.ConstructingParser
https://lampsvn.epfl.ch/trac/scala/ticket/4520


Maybe fixed, but not closed:

#2171 Compiler 2.8.0 hangs with -optimise option
https://lampsvn.epfl.ch/trac/scala/ticket/2171

#2080 It should not be possible to override concrete member types
http://lampsvn.epfl.ch/trac/scala/ticket/2080

#3457 specialize anonymous classes inside specialized methods
http://lampsvn.epfl.ch/trac/scala/ticket/3457


Bye and thanks,
