Hi Hakan,

I did this:

1. Updated my clone of main 6.0 to match the current tree.
2. Compiled the tree using BUILD/compile-pentium64-valgrind-max
3. Run "./mtr --suite=falcon"
4. Run "./mtr --valgrind --suite=falcon falcon_bug_22089

And observed this:

* I could run the falcon suite in step 3 - the tests run and pass normally.
* After doing step 4 I can see the valgrind stack in var/log/master.err. Here it 
comes again:
