Which you did not say, neither the message nor the patch itself
contained any hint that you investigated this at all nor
what the conclusions are.
I still don't think it a great idea to reduce the usefulness
of the whole valgrind test for those "few" failing ones,
but after finding the cause, fine.
But only with _proper_ documentation what this is about.
And possibly a bug report to valgrind - I am not sure
they will want to fix it, but there is a chance that they
just forgot about the redzone special-case when porting the
code from x86 to x86_64.

Well, it would offer a solution to the no-undef FATE test not being
able to use --valgrind (though I actually think that is not true,
it should be able to use --valgrind='valgrind --undef-value-errors=no').
