Hi,

if I call OSInstance::calculateHessian(double*, int rowidx, bool is_new) without having called OSInstance::getLagrangianHessianSparsityPattern() before, then this gives me a seg.fault at OSInstance.cpp:3670 (method OSInstance::getSecondOrderResults()), because m_vbLagHessNonz was not initialized before.

Thus, calling getLagrangianHessianSparsityPattern() helps, but I do not see why this should be required when I want only the hessian of a particular row.

This is OS/trunk rev. 2389.

Best, Stefan
