运行lli解释器时是否可以禁用异常？ 我想从崩溃中禁用以下内容，以便我可以进行内存分析-它当前在出现“释放后释放”错误后中止：

我正在使用的程序是：

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int *ptr;
    int *ptr2;
    int z = 10;
    int n = 5;

    ptr = (int*)malloc(n * sizeof(int));
    // ptr2 = (int*)malloc(z * sizeof(int));

    free(ptr);
    free(ptr);

    return 0;
}

然后我将其转换为LLVM IR，然后使用lli进行解释：

$ /usr/local/opt/llvm/bin/lli example_opt.ll > out.txt
lli(23782,0x7fff9934a380) malloc: *** error for object 0x7f9bee411780: pointer being freed was not allocated
