I did run this test and it worked fine.  I then proceeded to work towards making my \
simple test program blow up in the same way as krb5kdc.

I was successful.

I reproduced the failure by creating a little plugin .so that implements a function \
runAI() which simply calls AceInitialze()

I then implemented a small program which dlopen()'s my plugin  as well as the other \
standard plugins that krb5kdc loads.

When the dlopen()s use the flag RTLD_LAZY, the call to runAI() works.

When RTLD_NOW is used in all the dlopen()s, AceInitialze() gets a SIGSEGV.

In the morning I will debug further.
