Thanks.  Does it hang there indefinitely, with no further output for
minutes?  Does shibd still consume significant CPU according to top?
What are its memory figures?  Isn't your computer swapping heavily?  Can
you provide a full GDB backtrace (after installing
shibboleth-sp2-utils-dbgsym; please yell if you need precise
instructions).

Which version of shibboleth was working for you?
Can you share your shibboleth2.xml?
