valgrind (Ubuntu)

Bug Description

I'm working with Ubuntu 14.04 LTS (x86_64), fully patched. I compiled software using Intel's compiler, ICC/ICPC. Its a free download for free and open projects ().

Ubuntu 14's version of Valgrind is 3.10, and it produced a finding against an Intel library function "__intel_proc_init_ftzdazule" (also see When I downloaded and built Valgrind 3.11, the finding disappeared.

Please provide Valgrind 3.11 for LTS. It fixes practical bugs being experienced in the field.

Description-en: instrumentation framework for building dynamic analysis tools
 Valgrind is a system for debugging and profiling Linux programs. With its tool
 suite you can automatically detect many memory management and threading bugs,
 avoiding hours of frustrating bug-hunting and making your programs more stable.
 You can also perform detailed profiling to help speed up your programs and use
 Valgrind to build new tools.
 The Valgrind distribution currently includes six production-quality tools:
  * a memory error detector (Memcheck)
  * two thread error detectors (Helgrind and DRD)
  * a cache and branch-prediction profiler (Cachegrind)
  * a call-graph generating cache and branch-prediction profiler (Callgrind)
  * a heap profiler (Massif)
 It also includes three experimental tools:
  * a stack/global array overrun detector (SGCheck)
  * a second heap profiler that examines how heap blocks are used (DHAT)
  * a SimPoint basic block vector generator (BBV)
