16Tb is the limit for the 47-bit address space in x86_64 -- asan requires that much AS for the shadow. 
It also requires 4Tb for the allocator, so on x86_64 the current requirement is 20Tb.

With another address space the limits will be different.

No need to try a large app. 
Write a test that allocates (and does not deallocate) 32-byte chunks in an infinite loop and see how much RAM it can allocate.
