I am getting an unexpected fatal error when I try to add a constraint using the cplex.addLe(lhs, rhs, name) method in Java. The puzzling part is that the error isn't raised with the dozen or so other constraints that are added previously, and I don't seem to have this issue when running CPLEX 12.7. It also isn't handled by the concert exception handling. Instead, it kills the JVM. Has anyone had this same issue or have any ideas what might be causing it?

Here is the error message:

That looks like a problem in the native code (and that is why it kills the JVM instead of throwing an exception). Do you have a small code that you could share (either here or in private) that reproduces the crash?
