Hi,

   I've re-run with debug enabled but that wasn't much better:

I didn't get any out-of-memory errors. Also I didn't use Lua5.3, I only
have 5.1 and 5.2:

% dpkg -l |grep lua
ii  liblua5.1-0:amd64                      5.1.5-8ubuntu1
            amd64        Shared library for the Lua interpreter version 5.1

and

% ldd /usr/local/bin/osrm-extract |grep lua
	libluabind.so.0.9.1 => /usr/lib/libluabind.so.0.9.1 (0x00007f2207e1f000)

(0x00007f2207bed000)

None, using the standard foot.lua supplied with 5.4.0.

I'll try (a) on a 14.04 Ubuntu, (b) with an older OSRM, (c) with a
differently-produced Europe file to see what happens. Any other ideas
are welcome.
