+
+Currently the analyzer with basic store will report false alarm for such code:
+
+p[0] = "/bin/sh";
+p[1] = NULL;
+
+execv(p[0], argv);
+
+This is because BasicStore "collapses" all elements of an array into their base
+region. BasicStore should return UnknownVal() when getLValueElement. But that
+way will break current test in null-deref-ps.c.
