boost.test currently contains an assortment of new operators which IMO are not conforming to the C++ std.
The implementation basically looks like this:
p = std::malloc(n); if (!p) throw std::bad_alloc();
This ignores the fact the std::malloc() is allowed to return either 0 or some unique pointer on zero sized requests, whereas a C++ allocation function _must_ return a unique pointer for each zero sized request.
I think it is guaranteed that a C++ allocation request (operator new) is never asked to allocate 0 bytes, thus the problem doesn't exist. Regards, Daniel
