Segmentation fault

[jhanani2907]

I ran clang-6.0 in ubuntu 18.04. I am getting segmentation fault when I run this command. Could someone please help me?
Command:
clang-6.0 -Xclang -load -Xclang ../Spindle/Spindle/libSpindlePass.so -O2 -c test_loop_out_of_bound.c -o testloop.o
Output:
Begin: test_loop_out_of_bound.c
Function 0: main
Function 1: llvm.lifetime.start.p0i8
Function 2: sprintf
Function 3: llvm.lifetime.end.p0i8
Base: %1 = alloca [1000 x i32], align 16
inst: %9 = load i32, i32* %8, align 4, !tbaa !2
%1 = alloca [1000 x i32], align 16base
load inst ptr: %8 = getelementptr inbounds [1000 x i32], [1000 x i32]* %1, i64 0, i64 %7
