If you believe this happened as a result of a stack overflow in your
program's main thread (unlikely but possible), you can try to increase
the size of the main thread stack using the --main-stacksize= flag.
The main thread stack size used in this run was ....
ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
malloc/free: in use at exit: ... bytes in ... blocks.
malloc/free: ... allocs, ... frees, ... bytes allocated.
For a detailed leak analysis, rerun with: --leak-check=yes
For counts of detected errors, rerun with: -v
