Yes... on Solaris it ought to be using the code paths that call
krb5int_pthread_loaded in the support library. Among other things,
that function may call pthread_once a couple of times, and the
function passed (loaded_test_aux) will adjust a global variable
(flag_pthread_loaded) to indicate whether it actually got invoked.
So, some more things might help track down what's going on:
- set a breakpoint in krb5int_pthread_loaded, to verify that it's
getting called
- set a breakpoint in loaded_test_aux, to see whether it's getting
called
- examine flag_pthread_loaded after the process aborts, to see how
it's set

That's about what I'd expect, given the assertion message text...
