As I read ap_expr, it should be:

diff --git a/modules/proxy/mod_proxy_hcheck.c b/modules/proxy/mod_proxy_hcheck.c

         if (strcasecmp(parms->name, "HC") == 0) {
             *parms->func = hc_expr_func_fn;
-            *parms->data = NULL;
+            *parms->data = parms->arg;
             return OK;
         }
         break;

At least, with that in place it all works fine.
