Stack overflow in uniform_int_distribution

My program has a function for generating random numbers, and started crashing. Valgrind produces this error:

==6952== Stack overflow in thread #1: can't grow stack to 0xffe801000
==6952== 
==6952== Process terminating with default action of signal 11 (SIGSEGV)
==6952==  Access not within mapped region at address 0xFFE801FF8

==6952==  If you believe this happened as a result of a stack
==6952==  overflow in your program's main thread (unlikely but
==6952==  possible), you can try to increase the size of the
==6952==  main thread stack using the --main-stacksize= flag.
==6952==  The main thread stack size used in this run was 8388608.

My code:

std::random_device rd; 
std::mt19937 rng(rd());  
int rnd(int min, int max, std::mt19937& rng) {
    std::uniform_int_distribution<int> uni(min,max);
    return uni(rng);
}
rnd(0, 1000, rng);

I tried to look at the file it's referring to, but I don't understand a line of it. What is causing the segfault?
