--- Comment #1 from Petro Karashchenko <petro.karashchenko at gmail dot com> ---
Also the ambiguity of the issue is that excess read instructions generation
depends on type of the field. Excess reads are not generated when 8 bit types
are accessed and generated when data types greater that 8 bits are accessed.
