+Subject: [PATCH 2/2] server-mem-limit-test: Limit memory usage only when not
+ built witha sanitizer
+
+A build with -Db_sanitize=address crashes with failed mmap(), which is done
+inside libasan. The test requires 20.0TB of virtual memory when running with
+the sanitizer, which is beyond unsigned integer limits and may not trigger
+the bug anyway.
