Hi, yes, I'm having trouble as well.  

I'm crashing anytime I create a table, (-O2).  I just tried the 8/29 snapshot.
I've got an environment set up now to try a few things.  

Without -O2 it seem to be better. I see the same problem with 
create function as you.  Also many failures seem to the result
of some type not defined.  Is that expected?

Sorry to jump in so late here.
