Micah Kornfield commented on ARROW-6547:
----------------------------------------
It sounds like the diff-test is potentially worth fixing, I'll see what I can
do for this next release. I'm also interested to see how these would compare
with what MSAN ([https://clang.llvm.org/docs/MemorySanitizer.html]) returns,
unfortunately its not clear to me if "that can be recompiled from source,
including all dependent libraries." is actually a requirement or if it can be
limited to Arrow libs.
