This test program loads libgssapi_krb5, uses it minimally, and unloads 
it, all repeated twice.  The assertion failure means that the library 
initializer ran both times it was loaded, but the library finalizer 
didn't run in between.  So something is wrong with the library finalizer 
support for HP-UX as determined by include/k5-platform.h and the 
autoconf stuff.  If there is a flag to block unloading when building a 
shared library, like the ELF "-z nodelete" flag, that would be the best 
fix; see the lib_unload_prevented variable in config/shlib.conf.
