Chances are you haven't actually fixed all the endian issues. Once
you fix the obvious ones, in a non-trivial application you may very
well encounter less obvious ones that are harder to reproduce.
For example, code that accesses the same data as both a word and as
individual bytes probably has a lurking endian problem. Another is
code that depends on the layout of structures and the alignment of
data members.
Some problems that might otherwise be obvious overflow problems can
be subtly hidden. For example, if an integer word value isn't
particularly large and the bytes are swapped incorrectly, the
resulting value may be smaller and you may not notice anything
obviously wrong because the incorrect value is till within the valid
range.
