Segfault raptor_solutions.cpp

[koch-t]

On the latest dev snapshot, some occurrence results in a segfault:

[Switching to Thread 0x7ffff2fab700 (LWP 13411)]
0x000000000061c51d in navitia::routing::get_walking_solutions (clockwise=false, departs=std::vector of length 94, capacity 94 = {...}, 
    destinations=std::vector of length 117, capacity 117 = {...}, best=..., disruption_active=false, accessibilite_params=..., raptor=...)
    at /opt/navitia/source/routing/raptor_solutions.cpp:229

print final_rpidx
$1 = 4294967295

final_rpidx looks dodgy, will investigate later

Fixed by #379

If i do it on a debug-build (difference besides the -g and 03 flag is that Clang was used on the release build) i get a segfault at a different place:

handle_vj<navitia::routing::VisitorWalkingTime> (current_jpp_idx=<optimized out>, accessibilite_params=..., raptor_=...)
    at /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/include/g++-v4/bits/stl_iterator.h:728
728           __normal_iterator(const _Iterator& __i) : _M_current(__i) { }

which appears to be make #381 a duplicate issue
