--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
The test case here is more compelling than the one in bug 84474 and I agree
that it would be helpful to avoid the warning, although not at the expense of
true positives.  Short of deferring the strncpy -> memcpy folding I don't see a
way to do it.  Let me confirm this report with the hope that GCC can change to
do the folding later.
