Title:
  go programs operate in "32-bit" allocation mode

Status in “gcc-4.8” package in Ubuntu:
  Confirmed

Bug description:
  I am having long and interesting conversations with upstream about how
  to fix this properly, but we also need a fix in time for trusty.  The
  symptoms of this problem is that programs occasionally die with
  messages like:

  runtime: memory allocated by OS (0x7f67005000) not in usable range
  [0x8b00000,0x88b00000)

  I think the fix is just changing malloc.goc to put the heap at an
  address that is available to user space processes on linux aarch64.
