#2010: SEGFAULT in newnet

How to replicate:[[BR]]
-Start a skirmish game with map "concrete" ( with or without AI, though AI
helps,) and set it to start without bases.[[BR]]
-Crash
droidStartBuild assumes that if
{{{
psDroid->psTarget == NULL) &&
(psDroid->order == DORDER_BUILD ||
psDroid->order == DORDER_LINEBUILD)
}}}
then the pointer is valid.
So when this happens ( I added in a CHECK_STRUCTURE to make it assert at
the logical location.)
{{{
psStruct = (STRUCTURE *)psDroid->psTarget;
CHECK_STRUCTURE(psStruct);
if (!droidNextToStruct(psDroid, (BASE_OBJECT *)psStruct))
{
/* Nope - stop building */
debug( LOG_NEVER, "not next to structure" );
}
}}}
So it sounds more like a bug "that happens in newnet that could potentialy
happen elsewhere" rather that "a bug in newnet".
Anyways, currently the droid my debugger has:
{{{
Action: Move to build
Order: daction_none
target: null
target stats: res. lab
}}}
And apparently actionUpdateDroid can easily fall through to starting a
help build, which in this case it leads to dereferencing a null pointer.
