  Log Message:
  -----------
  [compiler-rt] assert max virtual address is <= mmap range size

If these sizes do not match, asan will not work as expected.

If possible, assert at compile time that the vm size is less than or equal to mmap range.
If a compile time assert is not possible, check at run time (for iOS)
