[Bug 1263447] Re: Crash on pathfinding using unconnected maps
Can you make your map available for someone (me?) to look at - that
crash is happening inside boost::graph library code - (or conceivably a
Mudlet helper function that we've plugged into the library code) and
something in the map data is not right - I'd want to do an autopsy on
that data to see what is breaking things...
P.S. I've just exposed my Email address id you can post the (compressed
if possible) map file!

Title:
Crash on pathfinding using unconnected maps
Status in Mudlet:
Fix Committed
Bug description:
Import the sample map with rooms 1,2 which area in area 1 and are not
connected. Then try to do getPath(1,2) - a crash happens.
This happens on Mudlet 2.1, Chris7/Mudlet2/mudletDev and SF master.
