Hi,
the PRF is attached.
We have a regression between ACE 5.4.2 to 5.4.3 when we call ORB::shutdown.
After we moved from ACE 5.4.2 to 5.4.3 we get a Segmentation fault in
ORB::shutdown without any changes in our code. What the code does is loading
and unloading an ORB with the service configuration facilities. I attached
the code for our DllORB class that we load/unload.
Why does ORB::shutdown Segmentation fault? I assume we did not do anything
wrong in the DllORB code, as it ran without problems on 5.4.2. Any help
appreciated.
Here's a gdb stacktrace
Program terminated with signal 11, Segmentation fault.
