ok, I was able to compile a version that does not blow pd up

obviously I have no idea of what I am doing and I did some things based on warnings I was getting, but then, I do copy the input first and then reorder the channels but I do get the exact same result as before, so it was all for nothing.

here's my new attempt, hopefully not too far from getting things right https://github.com/porres/pd-else/blob/master/Code_source/Compiled/signal/remap~.c#L34

cheers

if the input and output signals have the same channel count, they will alias each other, just like in regular single-channel objects.
actually, funny stuff happens for 4 multichannel input and 3 multichannel output, but I've seen that issue with single channel objects and I tried copying stuff from other objects in ELSE into this multichannel idea and failed.
You first need to copy the whole input signal to a temporary buffer (probably allocated in your object) and then copy the corresponding channels to the output signal.

I wonder if you can give me a better detailed strategy/steps.

thanks
