    libstdc++: Remove inheritance from elements in std::tuple


This problem occurs on just one of our LE systems and I am not sure why.  Can
this be related to PR90520?  The error is different.

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Some of these tests are sensitive to GDB and Python versions. Do they differ

I'll take a look at this tomorrow.
