Bug#910237: googletest breaks mathicgb autopkgtest: invalid cast

Dear maintainers,

With a recent upload of googletest the autopkgtest of mathicgb fails in
testing when that autopkgtest is run with the binary packages of
googletest from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
googletest             from testing    1.8.1-1
mathicgb               from testing    1.0~git20170606-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is contributing to the delay of the migration
of googletest to testing [1]. Due to the nature of this issue, I filed
this bug report against both packages. Can you please investigate the
situation and reassign the bug to the right package? If needed, please
change the bug's severity.
