Hi all
I am trying to use Boost library on 64 bit windows and it is crashing
whenever i call a boost function. I am using boost 1.36 with VS2008 and i
have used the bellow line to compile boost's 64 bit version.

bjam debug release threading=multi --toolset=msvc-9.0 architecture=x86

I am using BOOST_ALL_DYN_LINK preprocessor to link to boost.

It crashes after saying that heap may be corrupted. Also it works fine if
compiled for 32 bit windows. Here is a sample code that replicates the

#include "boost/filesystem.hpp"

int wmain(int argc, wchar_t* argv[])
        wchar_t path[] = L"c:/temp/test";

        if(boost::filesystem::exists(path) )
                printf("Path exists.\n");
                printf("Path does not exists.\n");
        return 0;


Here is the call stack at the time of the crash.
