Package: valgrind
Version: 1:3.2.3-1
Architecture: amd64
$ cat t.c
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
I compiled things static for a little more diagnostics, i.e. function names
below.
Basically same results with a dynamic binary. E.g. "valgrind ls"
$ cc -Wall -O2 -g -static t.c -o t
$ ./t
Hello World!
$ valgrind ./t

==19908== valgrind: Unrecognised instruction at address 0x451E22.
==19908== Your program just tried to execute an instruction that Valgrind
==19908== did not recognise. There are two possible reasons for this.
==19908== 1. Your program has a bug and erroneously jumped to a non-code
==19908== location. If you are running Memcheck and you just saw a
==19908== warning about a bad jump, it's probably your program's fault.
==19908== 2. The instruction is legitimate but Valgrind doesn't handle it,
==19908== i.e. it's Valgrind's fault. If you think this is the case or
==19908== you are not sure, please let us know and we'll try to fix it.
==19908== Either way, Valgrind will now raise a SIGILL signal which will
==19908== probably kill your program.
