Hi, There should be function call for free(tinfo) at the end of the function main() in profread.c and gss-perf.c. Otherwise, there would be memory leaks. The patches for main() in profread.c and gss-perf.c are the same as below. This is the similar issue as trunk@23559. commit ebfd96a98ccb8f7df042cadbeefa00ee4761b9fa Author: Ezra Peisach Date:   Thu Dec 31 23:18:16 2009 +0000     Free tinfo at end - so program runs with new memory leaks     git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23559 dc483132-0cff-0310-8789-dd5450dbe970 diff --git a/src/tests/threads/init_ctx.c b/src/tests/threads/init_ctx.c index 208104d..1629060 100644 --- a/src/tests/threads/init_ctx.c +++ b/src/tests/threads/init_ctx.c @@ -274,5 +274,6 @@ main (int argc, char *argv[])              100 * total / wallclock / n_threads);      printf ("Total CPU use per iteration per thread: %Lfms\n",              1000 * total / n_threads / iter_count); +    free(tinfo);      return 0;  } Young
