Segmentation fault on CPLEX when executed in subtasks

[Marcos Martín Pozo Delgado]

Hi,

I'm experiencing segmentation faults in the CPLEX shared object because invalid reads in the optimize_for_all_states() call when it is called over different subtasks. This does not happen always and I'm not sure if it depends on the subtask or it just happens sometimes when multiple CPLEX objects are created and used. The problem happens with the last version of CPLEX and also in version 12.10.

This is the code I'm using over subtasks created using each landmark of the original task as the only goal:

potentials::PotentialOptimizer optimizer(task, lp_solver, 1e8);
optimizer.optimize_for_all_states();

Any hint about how to solve this issue?

Thanks!
