The code throws an error complaining about column 0 because the
problem is an empty problem. The lp->mipmodel creation at line
20 of sos.cpp clones the lp at the time - which is empty.<br>
<br>
The coin_loadprob at line 96 adds columns to the lp - not the
cloned lp.<br>
<br>
Try using<br>
<br>
lp->Solver = new OsiXxxSolverInterface();<br>
lp->mipmodel = new CbcModel();<br>
OsiSolverInterface * solver = lp->Solver;<br>
lp->mipmodel->assignSolver(solver);<br>
<br>
Not sure what has changed from 2.8<br>

<div>Hi,<br>
<br>
</div>
I mentioned that I have been getting seg fault from Cbc
2.9 (downloaded about a week ago) when I tried to add SOS
to the problem. I have now managed to produce a program
that reproduce the crash. It happen when a CbcSOS object
is created, and not in addObjects(). <br>
<br>
</div>
<div>As the problem needed to produce this was quite small,
I was able to simplify the program to be in a single file,
which I attach to this post. If I made any mistake in
simplifying the program, I can send the original version,
which requires extra support files from our system to
compile.<br>
<br>
</div>
<div>The program is extracted from calls to Cbc from our
interface. The same calls worked with Cbc 2.8 (downloaded
nearly 2 years ago). <br>
<br>
</div>
Thanks in advance for any information or help in resolving
this problem.<br>
<br>
</div>
Cheers,<br>
