Different Output for Mac Silicon

[xsaschako]

Bug description

When we run certain tests, for example TestGraphSimulation.consistencyStochasticMobility, on the mac m1 we use the runga kutta method of boost.

There, while having the same input, the output starts to differ in the later digits after 2 iterations, this adds up iteration after iteration. This can be debugged in the try_step of the file controlled_runge_kutta.hpp.

Version

Mac

To reproduce

git clone git@github.com:DLR-SC/memilio.git
cd memilio
mkdir build
cd build
cmake ../cpp
make -j
cd bin
./memilio-test --gtest_filter=TestGraphSimulation.consistencyStochasticMobility

Old fail is fixed, but now:

[ RUN ] ModelTestOdeSecir.export_time_series_init_old_date

Expected equality of these values:
