Exactly. That's why I had the "blah" argument there. Actually on 
another system it segfaulted immediately while on this other system
I had to create the object twice. I guess it's just a matter of
when the freed memory gets used.

No rush. As I mentioned, it was actually a bug in my own code that
triggered this (and it would actually be an uncommon thing to do
anyway). So better to spend the time fixing it properly than getting
in a quick fix.

What about the instvar alias problem? Not exactly critical either
as I can work around it, but is there a fix coming up/available?
