> it would be great if std::malloc() could return how big the allocated memory block actually is, so we can leverage any extra space we might have gotten “for free”. I remember one of the Window allocation functions doing this, but I believe eliminated that behavior as it lead to old applications that didn't handle it correctly crashing. That is the danger with, say, adding a length value to free. Sometimes an off by one value will work fine, until someone tweaks how the allocator works.
