Bad NDDL can crash Eclipse #130

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
To replicate:
1. Go to PLASMA->examples->Light.  Right click on Light-initial-state.nddl and 
select "Run as NDDL Model."  Everything works as expected.
2. Now put the following line at the top of 'Light-initial-state.nddl':

fact(LightBulb.On on);

(This is incorrect NDDL because no LightBulb object exists yet)

3. Right click to run as nddl model.  Eclipse will crash.

I'm assigning to Tatiana, not because I think it's her fault, but because I've 
had success doing that in the past :).

Not Tatiana's fault for sure. There is a seg fault somewhere deep. With the 
model prepared according to Tristan's recipe above, do

EUROPA::PSEngine* engine = EUROPA::PSEngine::makeInstance();
engine->start();
engine->executeScript("nddl", model, true);
EUROPA::PSSolver* solver = engine->createSolver(config);
