llvm dev - Nov 2009 - [LLVMdev] -debug and -print-machineinstrs broken

Are these known to be broken right now? I get failure when using either.

Seems due to David's patches.

Ok.  Send me a testcase and I will fix.  This should be put into
the testbase.

Ok, it's faulting in SlotTracker with what looks like a bad Function.  One
of
the Argument values is corrupted.

I'm not abdicating responsibility, but at the moment I don't see the 
connection to my patches.  Anton, are you seeing something specific
as to the cause?

I will keep investigating.
