For some reason, aix sometimes executes the bogus function body. This should never happen as it lives in a no-execute section. It might be a transient permission blip as the heap grows. Add a small function to cleanup and synchronize the icache before jumping to the bogus function to ensure it causes a panic, not SIGILL.
