oh wow thanks! would you mind adding a test case like:

  TEST(CompletionTest, NoCrashDueToMacroOrdering) {
    EXPECT_THAT(completions(R"cpp(
      #define ECHO(X) X
      #define ECHO2(X) ECHO(X)
      int finish_preamble = E^CHO(2);)cpp")
                    .Completions,
                UnorderedElementsAre(Labeled("ECHO"), Labeled("ECHO2")));
  }

into clang-tools-extra/clangd/unittest/CodeCompleteTests.cpp ?
