Trying to port a mac program onto windows.  I've been having some
trouble getting the boost portion of it to work.  It appears to run
fine in release mode*, but crashes when debugged.  Below is an excised
piece of code that seems to replicate the problem, and works perfectly
in release mode but crashes when debugging.

I'm using Code::Blocks under XP, with Boost 1.37 with Mingw 3.4.5
(linking to boost_system-mgw34-mt-1_37.lib and
boost_filesystem-mgw34-mt-1_37.lib )

(Also: It doesn't crash when I run it in windows 95 compatibility
mode, but that's not really an option because that completely breaks
the program it's meant to be a part of).

Code:

#include "boost/filesystem/operations.hpp"
#include "boost/filesystem/path.hpp"
#include "boost/progress.hpp"
#include <iostream>

namespace fs = boost::filesystem;

int main( int argc, char* argv[] )
{
    fs::path p("chapters");
    fs::directory_iterator dir_iter(p), dir_end;
    std::cout<<"got here";
    return 0;
}

Outputs "got here" in release, just crashes in debug, with backtrace:

--------------------

Doing a similar build in Visual C++ 2008 with msvc builds of the
library, I get the error

Unhandled exception at 0x7c812aeb in filesystest.exe: Microsoft C++
exception: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::filesystem::basic_filesystem_error<boost::filesystem::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char>
>,boost::filesystem::path_traits> > at memory location 0x0012fb34..

whether I run a debug build or not.

--------------------

Compiling with the debug builds of the libraries
(X-mgw34-mt-d-1_37.lib) didn't produce significantly-different looking
other errors from the ones above.  Someone on the internet (
http://forums.codeblocks.org/index.php/topic,8429.msg64317.html#msg64317
) seemed to have a similar problem, but his solution isn't
satisfactory for me (for the reason given below).  Linking to
single-threaded builds of boost didn't seem to make a difference
either.

Any help with this would be really appreciated.

*I say 'appears to run fine' because, in the program that I'm trying
to port, in windows all I see is a blank window (it's an SDL
application); I can std<<cout directory structures from it though.
This is most likely an unrelated problem, but I can't start to debug
that until I've gotten this problem out of the way.
