Not a guru, but have thrown a few errors around.

It looks like it is the interpreter in OO that ends up in a confused
state, apparently trying to create a string out of nothing, perhaps
after the end of input. The reason could be:

* A programming error (thinko) in the macro
* A bug in the OO macro interpreter

Either way, it might be a good idea to ask on the OO dev/user lists as
well.
