[Bug 1386524] Comment bridged from LTC Bugzilla

[bugproxy]

------- Comment From willschm at us.ibm.com 2015-07-14 21:12 EDT-------
On at 14.04.2 LTS install;

local experimentation has confirmed that valgrind segfaults when built
out of the tools.  (apt-get -b source valgrind)

But does seem to work OK when built directly from those same sources.
Thus i suspect a subtle build option variation somewhere in the tooling.

Title:
  Update Ubuntu 14.04 with full Valgrind LE support.

Status in valgrind package in Ubuntu:
  New

Bug description:
  Problem Description
  ============================
  Valgrind in Ubuntu 14.04 only has the needed bit to compile.  It is not functional and crashes when used.
   
  The Ubuntu 14.04 includes the Valgrind tool using a snap shot of the Valgrind SVN repository from April 11, 2014.  The snap shot is  the Valgrind 3.9 release and an IBM patch allow the Valgrind tool to compile for PPC64 little endian.  However, the needed functional changes did not go into the Valgrind SVN repository until early August 2014.  The latest Valgrind release came out in early September 2014.

  We request that the next incremental release of Ubuntu 14.04 move to
  the Valgrind 3.10 release with the full PPC64 little endian support.
