+With GC_ASSERTIONS turned on in libgc/pthread_support.c, an assertion
+fails when running Allan's code.  
+
+Assertion failure: pthread_support.c:299
+
+The assertion is in the last line listed below:
+
+void GC_destroy_thread_local(GC_thread p)
+{
+    /* We currently only do this from the thread itself or from	*/
+    /* the fork handler for a child process.			*/
+#   ifndef HANDLE_FORK
+      GC_ASSERT(GC_getspecific(GC_thread_key) == (void *)p);
