I’m following along on ~up-to-the-minute -current AMD64 on my Thinkpad, and
only seeing the same memory errors as wiz’ original example.
Do the copyinstr in ::entry like this:
```
#!/usr/sbin/dtrace -s
#pragma D option destructive
#pragma D option quiet
syscall::unlink:entry
{
self->file = copyinstr(arg0);
}
syscall::unlink:return
{
printf("%d %s\n", pid, self->file);
self->file = 0;
}
```
And, forget that C file. It doesn't work under dtrace (and I don't even
recall if it ever did--probably why I commented it out...)
