==20246== If you believe this happened as a result of a stack
==20246== overflow in your program's main thread (unlikely but
==20246== possible), you can try to increase the size of the
==20246== main thread stack using the --main-stacksize= flag.
==20246== The main thread stack size used in this run was 8388608.
