Valgrind developers:

I am seeing a new test failure from the nightly regression run.

The error seems to occur starting with the commit:

commit 6faec425f13025084076e6fd2e1399a1834a3782
Author: Paul Floyd <pj...@wa...>
Date:   Mon Nov 9 09:37:17 2020 +0100

    Add testcase for C++14 sized delete

I was able to reproduce the error using an older version of g++.  I see
the error with g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

The error did not occur when I used a newer version of g++.

I didn't get to dig into the issue very much but hopefully that will
help to identify the issue.
