[dpdk-dev] Valgrind with DPDK - Error in "EAL: Segment sanity check failed"

[sreenaath vasudevan <sreenaathkv@gmail.com>]

Hi
I am trying to run DPDK 2.2 example application "l2fwd" with valgrind and
run in to the "Segment Sanity check failed" error.
I tried with standard valgrind-3.10 and the modified one (
https://github.com/bisdn/valgrind-hugepages) and run in to the same issue

Does anyone has any suggestions?

Following is the error log
