Description Martin Goldhahn 2005-07-26 12:45:48 UTC
The cause of problem is that the map that stores the worker properties is free'd
after being read. The values of properties, worker_env.worker_list stores just
pointers to the property map. After the property map is free'd the pointers are
invalid. This crashes if one tries to list the workers with the status worker.

Solutions: 1. copy the values (need proper allocation and freeing mem many places)
 2. keep the map during the whole lifetime of the ISAPI filter

The patch I attached uses the second solution.

I started with the first solution but this makes changes in many places necessary.
