Valgrind patched with support for DPDK (and rte_*alloc). STATICALLY LINKED: use --soname-synonyms=somalloc=NONE - DINAMICALLY LINKED: SONAME must be either lib*dpdk.so* librte_malloc.so*. NOTE: memory alignment is respected and implemented, but NUMA socket is ignored.

Valgrind with DPDK - Error in "EAL: Segment sanity check failed" #2
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 ran in to "Segment sanity check failed" error.
I then stumbled across your modified version of valgrind and tried from this repo, but ran in to the same issue. Following is the error.

Any suggestions on how to fix this?
