[Osi] Adding a row provokes a segfault

[Christophe-Marie Duquesne]

Hi list,

The following program segfaults:

#include <coin/OsiSolverInterface.hpp>
#include <coin/OsiClpSolverInterface.hpp>
#include <coin/CoinPackedVector.hpp>


int main(int argc, const char *argv[])
{
    OsiSolverInterface * solver = new OsiClpSolverInterface();

    CoinPackedVector vector;
    vector.insert(1, 1);

    solver->addRow(vector, 0, 1);

    delete solver;
    return 0;
}

Here is a backtrace with gdb:

#0  0x00330e59 in CoinPackedMatrix::appendMinorVector (this=0x804e9f0,
vecsize=1, vecind=0x804e878, vecelem=0x804e8a8) at
CoinPackedMatrix.cpp:1314
#1  0x0033102a in CoinPackedMatrix::appendMinorVector (this=0x804e9f0,
vec=...) at CoinPackedMatrix.cpp:1345
#2  0x0032da45 in CoinPackedMatrix::appendRow (this=0x804e9f0,
vec=...) at CoinPackedMatrix.cpp:239
#3  0x0019ad10 in OsiClpSolverInterface::addRow (this=0x804afa0,
vec=..., rowlb=0, rowub=1) at OsiClpSolverInterface.cpp:3041

Attached is an archive with this program and a Makefile. Set the OSI
flags according to your system.

Did I do something wrong?

Cheers,
