Closed as fixed if next.
If CPLEX finds a feasible solution before the root node solve, or a MIP start is provided, it is possible for one of the dual presolve reductions to find a better solution. In that case, functions that invoke the solve callback are involved, and a NULL pointer access can cause a segmentation fault. Workaround consists of disabling dual presolve reductions. Fixed in 220.127.116.11 RTC - 14645.
Disable dual presolve reductions. If that doesn't work, contact ILOG/IBM Optimization support for information on the undocumented functionality to disable the particular presolve parameter involved.
If one of CPLEX's heuristics that runs before the root node LP solve finds a feasible solution, a program with a solve callback can access a NULL pointer during a dual presolve reduction.
