so, when mimic was released. the "latest" centos was 7.4. by then, the shipped gperftools-libs was gperftools-libs-2.4-7 .
the tested Ceph is always compiled with the latest centos (7.5 at the time of writing), where gperftools-lib's version is 2.6.1. while the mimic's rados test suite is still pointing to centos 7.4.
<pre>
$ c++filt _ZdlPvm
operator delete(void*, unsigned long)
</pre>
this operator was introduced in gperftool 2.6.1, see https://github.com/gperftools/gperftools/commit/7efb3ecf37d88edf9cf9a43efb89b425eaf81d5e , search for "ENABLE_SIZED_DELETE". .
that's why we have the missing symbol on centos 7.4.
