It was due to my XKB settings (only the "=" keypad key gave a
KP_something keysym due to missing configuration for this key,
contrary to the other keypad ones). So, now that the "=" keypad
key gives a normal "=" keysym, the problem is no longer visible
in Emacs on my machine. However I'm still wondering about the
remarks below:
