Title:
  static binaries compiled with gccgo can fail to set up their address
  space

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

Bug description:
  As reported in https://code.google.com/p/go/issues/detail?id=6926, a
  static binary produced by gccgo will fail to start up around 60% of
  the time with a message like:

  runtime: address space conflict: map(0x7f72018000) = 0x7f69ef8000
  fatal error: runtime: address space conflict

  (there is a more detailed write up at https://groups.google.com/d/msg
  /golang-dev/wFW_ppyLZTM/4fJXzuROV1IJ)

  I'm attaching a patch (against gcc-4_8-branch, a different one will be
  required for mainline) that seems to work, but it could certainly do
  with some more extensive testing.
