Comment (by Richard Webb <richard.webb_at_[hidden]>):

 I think that it's complaining about the use of references in the if
 statements in the BOOST_FOREACH macro.

 I get the same 'uninitialized memory' warning if i do things like:

 {{{
 struct foo
 {
         operator bool() const
         {
                 return false;
         }
 };

 int main(int, _TCHAR*)
 {
         foo afoo;
         if (const foo& f = afoo)
         {
                 f;
         }

         return 0;
 }
 }}}

 or even just:

 {{{
 int _tmain(int, _TCHAR*)
 {
         if (const int& i = 0)
         {

         }

         return 0;
 }
 }}}
