Comment (by igaztanaga):

 This is a known problem of the MSVC STL implementation. However,
 basic_ios::init call should be called only once, as the standard does not
 give any guarantee to allow calling it twice (MSVC STL leaks in this
 case). As pointed in http://accu.org/index.php/journals/264 we need to
 take of a potentially throwing custom streambuf so that basic_ios is not
 destroyed without being initialized. This is not a problem for
 bufferstream (has nothrow constructors) but it could affect vectorstream.
 In this second case a null streambuf will be passed to initialize
 basic_[i/o]stream, which will call basic_ios::init. After that, the
 streambuf will be replaced with vectorstream.
