It is not just an intermediate result problem; you can have issues
even with single math free-form operations regardless of the directive
settings or use of BIFs.

An EVAL will always trigger an error on overflow.  This is intentional
and a good thing -- but it is not compatible with math opcodes.  For
example, the infamous (and hideous) date conversion MULT variants
which intentionally cause overflow do not work with EVAL.  (Actually,
I think the compiler should watch for these and refuse to compile them
-- even with MULT! <g>)
