mkgmap is looping in the simplifySortedRoads() routine, although it
will eventually complete after a very long time.

What I see happening is that, with your style, there are 17000+ roads
with the name "[49847]FT".  That routine is very slow with a large
number of roads with the same name which are actually connected
together.

So it depends on your style only because these roads (paths) are all
unnamed in the default style.

But that is just the proximate cause of the hang, the real root cause
must be elsewhere, as the trunk code does not have this very large
number of paths with the same name.

Hope that makes sense, it really all depends on if the paths named 
[49847]FT really should all have the same name in your style or not.
It could be that the locator branch fixes a bug that prevented them 
having the same name when they should have for example.
