Is it normal that the values of the parameters of gps.connect are still keept?

Yes, because of the scope chain from functions that you have defined in gps.connect.

You could:
- Define the functions outside, and just add them to the listeners by name
- Set the parameters to undefined when you're done with them
Again, is it normal that the comments at the top level are keept too?

Yes, they're in history - the second Espruino runs low on memory it'll delete those.

Ok, that's clear now: I have to review the connect function and make it much more memory and time savy.
The trace has no identified memory leak so far.
It has been running for a few hours and the free memory is just changing by a few 10s of JsVar back and forth: I guess this is induced by the length of the nmea sentences.

So far, the "compiled" functions have not been a problem since you solve the webide getting confused about the order of returned compiled function last week.

edit: Here is a memory status taken from just after the trace(Serial4) to now.
Apparently the size of gps and Serial4 are slowly changing, and getting smaller. I think this could be the result of some garbage collection...
edit2: Actually, it is because the GPS lost its position fix and thus some properties of gps went to NaN and so on...
edit3: It is worst than that: Serial4 is no more defined, I create a new psot about that
