[Bug 1071209] Re: memtest86 test #7 fails (random pattern error)

[ethana2]

I have been modifying my RAM voltages, multipliers, and timings for the
last three hours trying to pass memtest 4.2 on my fresh 64-bit 12.10
install machine. I was about to start tweaking the FSB. *headdesk*

Title:
  memtest86 test #7 fails (random pattern error)

Status in “memtest86+” package in Ubuntu:
  Confirmed

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.
