Hi

When using debug mode in windows with boost_filesystem there's "Debug
Assertion Failed!"  in _CtrIsValidHeapPointer

When operator new is redefined it causes windows_file_codecvt not to
be released with the matching release that it allocated it.

We reported this to Microsoft as seems it's a bug in their STL. But so
far, I tried with VS2012 and the bug seems not fixed...

There's a workraround in boost that we are using for the moment:

This has to be changed in path.cpp to fix it:

-    std::locale loc(global_loc, new windows_file_codecvt);
+    std::locale loc(global_loc, _NEW_CRT windows_file_codecvt);

Should this fix be applied in boost until is fixed on Microsoft's side?

This is a very nasty issue that will happen only with a redefined
operator new.  (For example we are using new with the sacalable
allocator of tbb).

Regards.

Pedro.
