+# The extract-tests leak some memory in the tests to confirm that
+# lua errors print tracebacks.
+# This appears to be because when these tests throw exceptions, the
+# osmium objects being processed are not freed. In production this doesn't
+# matter, as the exceptions bring down the entire osrm-extract process. In the
+# tests, we catch the error to make sure it occurs, which is why the
+# leaksanitizer flags it.
