7504	boost::interprocess::basic_vectorbuf calls std::char_traits<char>::pbump() with potentially mismatching data type	mbradshaw@…	Ion Gaztañaga	"`boost::interprocess::basic_vectorbuf::seekoff()` makes a call to `base_t::pbump()`, but the datatypes (may) mismatch for the parameter (and do on my system). `std::char_traits<char>::pbump()` takes an `int` (according to the standard), but `basic_vectorbuf()` is passing it a value of type `CharTraits::off_type`, which is implementation defined. Since `std::char_traits<char>::off_type` is `__int64` on my system, I am getting a warning about a conversion from `__int64` to `int`.

I don't know what the most appropriate solution is (maybe just a `static_cast`), but it would be nice to have this resolved so I can get back down to 0 warnings in my codebase.

I am using Visual Studio 2010 and the latest Boost (and I just check svn trunk and it has the same issue). I get this warning when creating a `boost::interprocess::basic_vectorstream` like so:
