Possible memory leak in Gurobi C++ API

I have a function, say func(). In func(), I create a GRB model with the code below:

GRBModel m = GRBModel(*env);

Variable m takes about 5 MB after I call m.optimize(). Ideally, when func() is finished, all variables created on the stack will be destroyed, including variable m. However, it seems the 5MB memory used by variable m is not released. To be clear, I have already manually freed objects returned by Gurobi methods during the modeling process, e.g., new variable array returned by GRBModel::addVars.

As I have to call func() up to 10 thousand times in my program, memory drains very quickly. I'm thinking if it is possible that we have memory leak issue on GRBModel class. Any comments are appreciated.

  Hi,

  Could you post a minimal working example reproducing this issue?

  Best regards,
