Subject: [boost] heap corruption on windows due to windows_file_codecvt

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.
