 That's an old unmaintained one which really should be removed.
 Please try one of those two:

 https://github.com/sosm/cbf-routing-profiles/blob/master/foot-city.lua
 https://github.com/sosm/cbf-routing-profiles/blob/master/foot-hiking.lua

 They work fine against OSRM versions 0.3.3 - 0.3.9.

Ok, many thanks for your answer; I followed your instructions and was
able to use those profiles! So that's great, and thank you again. ;-)

Unfortunately the initial problem isn't solved; some points in Paris
(lots of them) are apparently non-navigable by foot -- many times, for
instance, at the center of roundabouts (but not only, and not always).

It's quite strange since when one asks to navigate to/from the middle
of the river, or the center of a building, or the middle of a highway,
a path is found that goes to the nearest accessible point.

So it seems, in principle, a path should always be found? What makes
pathfinding fail in some cases?

I'm using the most recent data published by geofabrik two days ago,
and upgraded Project-OSRM to 3.9.

I'd really like to get to the bottom of this: would it help to run
osrm in debug mode?

Any other idea?

Thanks,
Regards,
EB

 you can exclude all ways with area=yes from routing. Simply add something
 like this in way_function() of your profile: 
 
 if way.tags:Find('area') ~= '' then
return 0
 end
 
 But this might do more harm than good.


+1, I wouldn't exclude pedestrian areas from routing. They should of course be 
connected, many situations would become islands if routing on areas is off. 

One issue that currently is yet to solve afaik are pedestrian areas defined by 
multipolygons, their ways should also be integrated into the graph

cheers,
