Huh?

I'm about 1000% sure that there's a buffor overflow or something
similar. Somebody (probably your code) writes to memory where it better
should not. Somebody overwrites (compiled) expressions for the
evaluator, and later the evaluator complains about unknown tokens.

So either double-check your code for bounds checking, or send me the
patch (as described in my other mail), and I'll have a look at it.


bye, Michael
