Please, check that ctx isn't a null pointer. Use update_last_error to raise an error accordingly.

Also, check that f and b aren't null.

Do we really need to check null pointers explicitly that way?
It's easy to debug SIGSEGV's caused by null pointers.

This is what we did in the other function, it's debatable :-).

Does it support floats (I think it does not matter since the bits can be interpreted as a float, but I prefer to ask)?

Floats are passed in different registers and it would be very complex to handle this case. I think it's better to just support integer parameters.

So trampoline doesn't work with floats. It's important to know!
