==30968== If you believe this happened as a result of a stack
==30968== overflow in your program's main thread (unlikely but
==30968== possible), you can try to increase the size of the
==30968== main thread stack using the --main-stacksize= flag.
==30968== The main thread stack size used in this run was 8388608.
