        <pre>Hi,
when I used clang9.0 and the latest version to output the value that
NISLParameter0 points to, they both outputed 1. While other compilers, such as
gcc and intelc,reported Segmentation fault.

TestCase:
#include<stdio.h>
int main(void)
{
    int *NISLParameter0;
    printf("%d\n", *NISLParameter0);
    return 0;
}

Command:
./clang/version_latest/llvm-project/build/bin/clang testcase.c
./a.out

Version:
clang9.0.0 && clang10.0.0

Output:
1

Expected output:
Segmentation fault

Is this right for the clang complier? Looking forward to your reply.</pre>
