+// RUN: c-index-test -test-load-source-reparse 1 local %s | FileCheck %s
+
+// See PR 21254. We had too few bits to encode command IDs so if you created
+// enough of them the ID codes would wrap around. This test creates commands up
+// to an ID of 258. Ideally we should check for large numbers, but that would
+// require a test source file which is megabytes in size. This is the test case
+// from the PR.
