Tell valgrind not to worry about reading from unitialized memory. so, for whatever reason this doesn't work on my setup. Steven, what is needed to have these valgrind hints enabled ? Are these valgrind hints enabled by default ? BTW, this also clearly shows that at this point this PR is unrelated to SLSR and fixed.
