Deleting a MultiFileIndex is not possible

[AlexanderFabisch]

While running the following program, it hangs at delete multiIndex; and won't finish. Valgrind gives me the following error:

==13922== Conditional jump or move depends on uninitialised value(s)

    delete multiIndex;
    std::cout << "deleted" << std::endl;

@hemker Do you have an idea?

[AlexanderFabisch]

OK, I solved this issue for me: pocolog_cpp must be compiled with C++11, e.g. set(CMAKE_CXX_STANDARD 11).
