 In Visual Studio 2015 it can lead to stack corruption if I instantiate
 std::basic_istream with the same types in two compilation units, and one
 of them forward declares the template and the other doesn't.

 I originally run into this problem when I called a funtion in a library
 that called boost::lexical_cast. The source file containing the function
 included a header from interprocess, which included
 interprocess/detail/std_fwd.hpp which contains a forward declaration of
 std::basic_istream.

 Unfortunately std::basic_istream was also instatiated with the same types
 in my main program (but there was no forward declaration).

 I presume this can happen with other templates as well, but so far this is
 the only one I found.

 The same code was working fine with Visual Studio 2013.

 I created two small solutions:
 - BoostStackCorruption_VS2015: using boost::lexical_cast and an
 interprocess header
 - StdStackCorruption_VS2015: using only std but with lines coming from the
 insides of lexical_cast and interprocess/detail/std_fwd.hpp
