Hi Martijn, "Illegal Instruction" is actually a proper processor fault (ie. your processor noticed a problem, and jumped to an interrupt routine telling your OS that hey, things need to be handled) that happens when one tries to execute code that isn't actually code or uses an instruction that your CPU doesn't have.
I'm pretty optimistic that hackrf.dll wasn't compiled for a CPU that's incompatible to yours, so this might essentially be a bug – either in the hackrf driver dll (which might be jumping into machine code that isn't code), or in the way the windows DLL loader is used. Hm. Maybe even a compiler bug. Now, I have to admit that under Unixes, I'd know how to debug this, but under Windows, I'm out of my depth. So if you happen to be more capable than I am with that, you could try to run "python C:\path\to\your\flow_graph_python_file.py" in a debugger and see where it crashes. But even then, I don't know if things would be easy to figure out.
