Subject: [gecode-users] operator = for NaryUnion

 

Hi,

In Gecode 4.1 creating n-ary union of variable ranges and assigning to a
NaryUnion causes a segmentation fault, whereas in Gecode 3.7.3 it seems to
work: 
Region myRegion(*this); 
Iter::Ranges::NaryUnion narr[2];
IntVarRanges* varRange = myRegion.alloc<IntVarRanges>(x.size()); // x is
IntVarArray variables of the model 
for (int r=0; r < x.size(); r++) {
    varRange[r].init(x[r]);
}

narr[0]  =  Iter::Ranges::NaryUnion(myRegion, varRange, x.size());

If we instead create only one NaryUnion then it works fine in Gecode 4.1:
Iter::Ranges::NaryUnion uni(myRegion, varRange, x.size());

I also attached a minimal code demonstrating this issue. Do you think if
there is something I'm missing here?



Cheers,
Farshid
