Why do I receive a segmentation violation when I try to run a SimMechanics 2.1.1 (R13SP1) demo on Linux?

I am trying to simulate a SimMechanics model, such as the mech_dpen demo. When I start the simulation, I receive a segmentation violation.

This has been verified as a bug in SimMechanics 2.1.1 (R13SP1) in the way that the Java Virtual Machine handles SimMechanics models on some installations of Linux.

Currently, to work around this issue, try starting MATLAB without the JVM enabled.

 matlab -nojvm
