In Ubuntu, the attached patch was applied to achieve the following:

  * Mark optional weak symbol as optional in the debian/symbols file.

Both the _ZNSt10* symbols seem to be optionally weakly defined leakage
from libstdc++, and show up intermittently.  You already covered the
first, however I noticed that the second has the same issue (and does
not end up in the final binary on at least ppc64el).  This patch fixes
the issue in the package.
