In the initialization code, shib_child_init, you setup the
cleanup functions

  apr_pool_cleanup_register(p, NULL,
    &shib_exit,
    &shib_child_exit);


The second function, the child cleanup, is called when an 
apache process has just fork'd and is about to do an exec
of the cgi.  At this point not much should be done in the
child cleanup function - likely nothing at all, since
open file descriptors will be closed anyway.  Especially
the config->term() cannot be called.

Replacing the cleanup register statement with

  apr_pool_cleanup_register(p, NULL,
    &shib_exit,
    apr_pool_cleanup_null);


appears to fix the problem.

p.s. I still think cgid is the way to go.
