Re^4: Map a string to an arrayby BrowserUk (Pope)

(And BTW, congratulations on being able to work with a system having at least 128 Terabytes of system RAM — or do I misinterpret the reference address of 0x7ffafc013bf8?)
With virtual memory, heap does not have to be contiguous.
This C program allocates a single page of memory starting at the 4GB base address and then doubles the base address each time until it fails:
I only have 8GB of ram, but the last time the above succeeds:
It allocated a page at a base address that is 4096 GB. At that point the process is only using 668k of memory.
4096GB is 2^42 which reflects that my 64-bit processor actually only has a 44-bit virtual address space.
