Valgrind errors on ppc64le with gcc and clang builds
I am trying to build Luajit on ppc64le. I had used the ppc64le supported code. The code is building without issues. But I am seeing few failures when Valgrind is enabled with gcc or clang compiler. I am sharing the test suit run here (removed the few test cases output which are passed to minimize log). I checked the code but I could not notice the susceptible code line which could be causing memory leak. However I had fixed one error related to unfinalized variable. Please have a look and let me know suggestions or if it could be ok to live with these errors? Note that I had not seen these errors on AMD build.
Build commands (same as Travis build using valgrind with gcc/clang)

I've got the ppc64le port PR #77 for luajit2 which includes some fixes on top of the ppc64le patches that were in Debian, etc. months ago. Can you please try that?
@siddhesh - I tried the patch and also the build the LuaJit out of source https://github.com/siddhesh/luajit2/tree/siddhesh-luajit2-ppc64le I was getting the Valgrind errors there as well.
Just for the reference for Valgrind errors, below are the travis ppc64le builds https://travis-ci.org/SantoshMagdum/luajit2/jobs/607570941 https://travis-ci.org/SantoshMagdum/luajit2/jobs/607570942
