[Open Babel] segmentation fault in OBBuilder.Build()

[Martin Guetlein]

Hello All,

I came across an example that causes OBBuilder to produce a
segmentation fault (g++ version is 4.4.3, openbabel-2.2.3). See code
below.

Best regards,
Martin


#include <iostream>
#include <openbabel/mol.h>
#include <openbabel/obconversion.h>
#include <openbabel/builder.h>

using namespace std;
using namespace OpenBabel;

int main(int argc,char **argv)
{
        OBMol * mol = new OBMol();
        OBConversion obconversion;
        obconversion.SetInFormat("smiles");
        //obconversion.ReadString(mol, "C1(N=C(NC(C)C)N=C(N=1)OC)NC(C)C");
        obconversion.ReadString(mol,
"OC1=CC3=C([C@@]2([H])CC[C@@]4(C)[...@](CC[C@@H]4O)([H])[C@@]([H])2...@h](CCCCCCCCCS(CCCC(F)(F)C(F)(F)F)=O)C3)C=C1");
        cout << "formula "<< mol->GetFormula() << "\n";
        cout << "Has3D: " << mol->Has3D() << "\n";
        OBBuilder builder;
        builder.Build(*mol);
        cout << "Has3D: " << mol->Has3D() << "\n";
        delete(mol);
        return 0;
}
