Comment (by pulkomandy):
The whole story is a bit more complex. But basically, the thing is, the
limit is gone, but the memory allocator isn't aware of it yet. So, with
malloc() you can only get about 2GB. But you can use mmap or create_area
and then do your own things there, and for that, the limit is removed.
We have at some point moved to rpmalloc which removes that limitation, but
it turns out, it needs quite a lot of memory space (being designed for
64bit systems where this isn't a problem) and on 32bit it would run out of
memory even earlier. So we have reverted that for now. We will be testing
other allocators at some point (possibly the musl one) for the default
setting.
But for debugging, we use yet another (intentionally simpler) allocator.
We can maybe tweak its initial size reservation on 64bit?
