Summary:
Problems with Manager class initialization

Detailed description
It seems like that something is going wrong with Manager class setModel()/ setIntegrator(). Not all model files but model file with muscles causes a crash with commented initialization code below. (crash with chain_2_hinge_muscle.osim, no crash with chain_2_hinge.osim) I'm using opensim v2.4 api for VC9 users. Model osim(modelFileName); SimTK::State& si = osim.initSystem(); osim.computeEquilibriumForAuxiliaryStates(si); SimTK::RungeKutta3Integrator integrator(osim.getMultibodySystem()); integrator.setFixedStepSize(.001); // works well Manager manager(osim, integrator); // crashes // Manager manager; // manager.setModel(osim); // manager.setIntegrator(&integrator); manager.setInitialTime(startTime); manager.setFinalTime(finalTime); manager.integrate(si); // -> crash occurs here when commented manager initialization code is executed.
