Problem:

ORB crashes due to wrong order of calling orb->resolve_initial_references

Resolution:

Product Name: VisiBroker for C
Product Version: All
Platform/OS Version: All

Problem Description

When user calls orb->resolve_initial_references("ORBPolicyManager") before orb->resolve_initial_references("RootPOA"), the ORB may crash with a similar stack trace when resolve_initial_references("RootPOA" ) is called.

Resolution:

The following are the two resolutions to this issue:

1. To ensure that call to orb->resolve_initial_references("ORBPolicyManager ") happens after orb->resolve_initial_references("RootPOA"). When the application is a multi-threaded, it is the user"s responsibility to ensure correct sequence of call between the two.
2. To change the policy from CORBA::SET_OVERRIDE to CORBA::ADD_OVERRIDE through the CORBA::PolicyManager::set_policy_overrides().
