lldb Immediate exit with status = -1 lost connection

Question

I can't get llbm to run on my (2020 Intel) Macbook (with updated command line tools).

I create a file test.c containing:

#include <stdio.h>

int main(){
    printf("hello world\n");
}

and then run clang -g test.c -o prog. Now I run lldb prog and get the following output:

lldb prog
(lldb) target create "prog"
Current executable set to '/whatever/prog' (x86_64).
(lldb) run
Process 3934 launched: '/whatever/prog' (x86_64)
Process 3934 exited with status = -1 (0xffffffff) lost connection

Does anyone know what is going on here?

Answer 1

Turned out that reinstalling Xcode (instead of just updating the command line tools) fixed the issue.
