+# Alpine-linux based containers use musl implementation of libc which causes
+# valgrind to emit false positives. Therefore we run UT with valgrind in
+# a separate build stage that uses ubuntu container with GNU libc installed.
+#
+# NOTE: The valgrind false positive problem could also potentially be solved
+# with valgrind suppression files but that kind of approach may be fragile.
