[Bug 1071209] Re: memtest86 test #7 false positives (random number sequence error)

[Chris J Arges]

Linked a branch with a fix that works for me in raring.

There seems to be a couple approaches for fixing this. The Suse bug has
the small change to clobber the additional register and that seems to
work. While the RH bug uses the C code in test.c instead of the
optimized assembler to generate the proper binaries. I took the Suse
approach for fixing this bug.

I noticed that there are uncommitted changes in the bzr development branch. So adding quilt didn't work so well.
To build I had to do an additional dpkg-source --commit to add these changes to a patch before building.
What's the proper way to do this so the package is in proper shape for patching?

Bug description:
  Trying to check the memory at newly bought notebook I found a bug in
  the memtest86+ version 4.20 in ubuntu 12.10, in ubuntu 12.04 it is ok.
  The bug is reported at least in Fedora and Opensuse. It is assumed
  that the bug is caused by the gcc-4.7.

  It is easily  reproducible - select the test #7 in memtest or just
  wait till it - starting from the 129Mb it will report a lot of errors.
  I have checked it on three different systems , two of them I use on a
  daily basis and would note if RAM is really bad.
