进程终止，状态为-107374167(Process terminated with status -107374167)

 我试图打印给定数字的素数因子。 我的代码适用于某些输入，但对于其他输入，它会被终止，我无法理解为什么。 
 
 样本输入： 
 
1
561473
 
 输出： 
 
2
 
 样本输入： 
 
1
10093
 
 程序终止了。 
 
 在某些时候，我认为它可能是浮点异常，但我无法弄清楚原因。 我试着调试每一行代码，发现程序终止于这行代码： 
 
while(ull(n%mem[j]) == 0) {
 
 我仍然无法理解为什么此代码仅针对某些特定输入而中断。 我也试过没有类型铸造，但它仍然给我同样的问题。 我试图打印异常，但程序刚刚终止，它没有打印任何错误。

I am trying to print the number of prime factors of a given number. My code works fine for some inputs, but for other inputs it's getting terminated and I can't understand why. 
 
Sample Input:
 
1
561473
 
Output:
 
2
 
Sample Input:
 
1
10093
 
And the program terminates. 
 
At some point, I thought it might be floating point exceptions, but I couldn't figure out the reason. I tried to debug every line of code, and found that the program terminates on this line of code:
 
while(ull(n%mem[j]) == 0) {
 
I am still unable to understand why this code breaks only for some particular inputs. I have tried without type casting also, still it gives me the same problem. I tried to print the exception, but the program just terminated, it didn't print any error.
