That actually comes from the cleanup code run at process termination or when a
library is unloaded.
(The assert() macro prints "__EX"?? We shouldn't be doing anything to override
the OS version of the macro, so that looks kind of poor....)
It's indicating that a key for thread-specific data (managed through a layer of
indirection in the support library) is being deleted without having been
registered, or after having already been deleted. Usually this means one of
several things -- the library initialization functions aren't being run, or the
cleanup functions are getting run more than once, or multiple copies of some of
the libraries are getting loaded in the process (resulting in multiple
instances of cleanup functions to run at exit), all using the same instance of
the support library.
Without an AIX system to test on, I can't tell you much more than that....
