I just tried running this in a VM where the counters are unavailable and got the following output:

$ ./poop echo
poop [1/1] 'echo'... thread 305373 panic: reached unreachable code
Unable to dump stack trace: debug info stripped
Aborted (core dumped)

I was hoping I might use some functionality of the program even if counters are unavailable. I am making an assumption that the problem is caused by the lack of counters; in an attempt to learn more detail, I was unable to build this using zig 0.10 on nix, I got an error about std.Build not being defined.
