Now I do :-(.  FunctionCache needs to be a read-only data structure;
it can't contain the argument block that's built for an individual call,
because the same expression tree might be invoked recursively while
filling in the arguments for a function.  I'm surprised no one has
noticed this before.

I'll fix it for 7.2...
