STEPS TO REPRODUCE
1. ❯ cat helloWorld.c 
#include <stdio.h>
int main(int argc,char**argv){
puts("hello world");
return 0;
}
2. ❯ gcc -g helloWorld.c
3. ❯ ./a.out 
hello world
4. ❯ valgrind ./a.out

==722282== Your program just tried to execute an instruction that Valgrind
==722282== did not recognise.  There are two possible reasons for this.
==722282== 1. Your program has a bug and erroneously jumped to a non-code
==722282==    location.  If you are running Memcheck and you just saw a
==722282==    warning about a bad jump, it's probably your program's fault.
==722282== 2. The instruction is legitimate but Valgrind doesn't handle it,
==722282==    i.e. it's Valgrind's fault.  If you think this is the case or
==722282==    you are not sure, please let us know and we'll try to fix it.
==722282== Either way, Valgrind will now raise a SIGILL signal which will
==722282== probably kill your program.
