What I meant was that you can be assured that std::allocator<> directly or indirectly uses malloc() because what I said. Custum allocators are almost never used since there's much complpexity in providing a full-featured allocator; imagine you've to provide the ability for the allocator to be rebound via typename allocator_traits<alloc>::template rebind_alloc<new_alloc> for any type, so you have to provide nearly everything a C-allocator has to provide. No one does that; it's mich easier to replace the whole allocation by replacing it by a thread-cache malloc() implementation.

No, you cannot be assured of that. If you don't believe me, see the C++ standard.

That doesn't make it so, and it's actually quite unreasonable. No experienced C++ developer will make that assumption.

This would still require access or influence over the main executable, which I (and many other C++ developers) do not have.

We have a large C++ library which uses strings and STL containers with a custom allocator built on top of the Intel TBB allocator. OTOH, all third-party C or C++ libraries and any host executables where our library might be loaded into still use whatever they want, typically standard malloc(). It would even be conceptually impossible for our dynamically loaded library to change the process malloc(), it would be far too late for that.

C++ containers can use >>> a custom allocator/deallocator in the same program that also includes >>> C code, too, ... >> They don't. > As usual, you are wrong. It's quite common in some circles. ... It's quite stupid to do that. You have to implement an allocator which can be rebound for all types with typename allocator_traits<alloc> ::template rebind_alloc<T> since you can't anticipate what the STL -containers rebind to, i.e. you have to write an allocator whith the full capabilities of malloc(). That's much work and it's almost impossible to beat the performance of common replacement-allocators. So it's just the best way to replace malloc() which is indirectly or directly used by std::allocator<> on all platforms. > None of which you've ever had any experience with; nor have you exhibited > the programming skills (or interpersonal skills) to survive in those circles. I've already built a custom std::allocator<> replacement for special cases where the allocator can be assumed not to be rebound (vector<>). And I would be able to write an efficient allocator like mimalloc; but I wouldn't have invented the basic structures for that - and you not as well.

Is it quite reasonable to argue with Bonita? (I only see reponses to
Bonita, not Bonita's own posts.)

The two of you are going round in circles. We all know what the C++ standards say about allocators here, and that they specifically say there is no requirement that malloc be involved in global allocators. We all know that library implementations can make use of extra knowledge about the implementation, in a way that user code cannot (at least not while remaining portable and avoiding undocumented and unspecified behaviour). We all know there is nothing in the C++ standards or documentation to suggest that you can "replace malloc" and assume that will change the global allocator. We all know that even if there were such a guarantee, it /still/ would not stop an implementation from being able to use additional knowledge about its own malloc when that is being used. I suspect that deep down, Bonita knows it too. Please leave it at that, unless there is actually any new information. This "Oh, no, you can't", "Oh, yes, you can" silliness just annoys people. Bonita is fanatically ignorant. The more you show she is wrong, the more she will dig in and insist that she is right. You cannot convince her - all you can do is make sure that no one else is fooled by her misconceptions, and you've done that already. That was complete dozens of posts ago. It's time to move on.

That's only a matter of someone's personal opinion. Others opinions is that it is completely unreasonable.

That's not an opinion but a reliable fact that all C++ standard -libaries actually use malloc() indirectly to make the whole memory-allocation replaceable.

Ok, you go ahead and write some code that depends on it, then wait when it breaks, inevitably, after a compiler/library upgrade, then get back to us. We'll figure out whether it's a bug, or not, at that time.

In particular, since C++14 (IIRC) there are sized overloads of delete which open the possibility of having more efficient memory allocation systems than traditional malloc/free as the heap no longer has to track the sizes of the allocated objects. (That has always struck me as a poorly considered aspect of C's malloc/free, leading to significant inefficiencies.) And even if Bonita was right that everything ends up in a call to malloc, she would /still/ be wrong. Malloc is part of the implementation - the implementation can have a way to find out the size of the memory actually allocated (since it knows all the details of the heap implementation), and make that available to other implementation code such as the C++ container library.
