@wdconinc volunteered to have a look at this. Let us know if this is still relevant.

Could you add a test case where the parameters are inside the beampipe volume, but the target perigee parameters are outside?

We could potentially flag the failing test as [expected failure](https://www.boost.org/doc/libs/1_65_1/libs/test/doc/html/boost_test/testing_tools/expected_failures.html) and merge it already.

This currently includes changes from #1507.

CI failures (so far) seem to be a GCC8 bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86594 I think this is ready for review.

I pushed a workaround.

@tboldagh thoughts?

Ok I've marked this as backward breaking now. Should we get this in @tboldagh?

Still need to update the memory stats calculation

Ok I think this is ready now. @tboldagh would you be able to have another look?
