Boost.Interprocess v1.66 - get_bootstamp segfault with C#

Hello,

I have problem with Boost Interprocess. I create C DLL Library which I Marshall  from C to C#.

I described problem in [StackOwerflow](https://stackoverflow.com/questions/49383042/boost-interprocess-v1-66-get-bootstamp-segfault-with-c-sharp)

Is this behaviour bug or my fault? What i'm doing wrong?
