If you are testing shared libraries, please remember that AIX caches publically-readable shared libraries by default for improved performance. If you change the shared library, AIX may still use the stale version it has cached. If the read-other permission bit on the shared library is _on_, then it goes into the shared text segment. If the read-other permission bit is turned _off_, then it is considered a private object and is loaded into the private data space, destroyed when the application exits. When developing a shared library, it is safest to turn off the read-other bit. When the library goes into production, it should be installed with the read-other bit enabled. The AIX "slibclean" command will clear the shared text segment. The command requires root permission. David
