I'm starting to think that it maybe impossible to override new and
new(nothrow) on project-local basis, which is what my option IV) was.

I tried using the actual implementation as well, but it doesn't work due to
cruntime.h being proprietary (i guess that's why it'snot found):

#include <cruntime.h>
#include <malloc.h>
#include <new.h>
#include <stdlib.h>
#ifdef WINHEAP
#include <winheap.h>
#else /* WINHEAP */
#include <heap.h>
#endif /* WINHEAP */

void *__cdecl operator new(size_t size) throw(std::bad_alloc)
{
    //char *p = ::new char[size];
    void *res = _nh_malloc( cb, 1 );

    if ( res == 0) {
        // TODO: log it
        throw std::bad_alloc();
    }

    return res;
}

void *__cdecl operator new(size_t size, const std::nothrow_t&) throw()
{
    char *p;
    try
    {
        p = new char[size];
    }
    catch (std::bad_alloc)
    {
        p = 0;
        // TODO: log it
    }
    return p;
}

I guess i'm giving up on this, and staying on choice III). What i'll do
though, is probably try to add a new handler that just logs an error message.
