+// RUN: %clang_cc1 -fsyntax-only -std=c99 %s
+
+// This test simply tests that the compiler does not crash.  An optimization
+// in ParmVarDecls means that functions with fewer than 256 parameters use a fast path,
+// while those with >= 256 parameters use a slow path.
+//
+// Crash was reported in PR 10538.
