pgrouting crashes and restarts the postgresql server when searching for endpoints in 2 disjoints graphs

[dkastl]

I have

apt-show-versions postgresql-9.1-pgrouting postgresql-9.1-pgrouting/precise uptodate 2.0.0-release-ppa1~precise2

Whenever I do a search http://docs.pgrouting.org/dev/src/astar/doc/index.html between two end points in disjoint graphs, I get the error error sending I/O to backend and my postgresql server crashes and restarts. Why doesnt this simply return a no route found?

This is a crash it needs to be trapped in 2.1.0

Note to self: Uses boost It does have the try/catch block. https://github.com/pgRouting/pgrouting/blob/develop/src/astar/src/astar_boost_wrapper.cpp#L130 and here https://github.com/pgRouting/pgrouting/blob/develop/src/astar/src/astar_boost_wrapper.cpp#L201 By first glance on the current code, I can't see what is wrong.

Astars code has being rewritten, there is no sample test case to test if this issue was fixed, I tested on the sample data that has disjoint graphs with no crash. If the problem persists, open a new issue
