Interesting...

Could you run it in debug mode (-dn) and send me the log file? Maybe it
has some interesting findings in it.

On valgrind and helgrind: both is fine. If the problem is reproducible,
first run it under the memory checker and then the thread checker.
Helgrind will report a couple (20 or so) exceptions at the END of
program run, that is fine. Any other exception - in either of both - is
interesting and probably helpful.
