Thanks for finding this error. Concerning si::universal-error-handler,
this is done by ancient code in spaderror.lisp. wh-sandbox constains
code to handle errors using Ansi condition system, but for GCL I still
used old handler. The patch below unconditionally switches error
handling to Ansi way (so it will probably break non-Ansi GCL).
The algebra build should work with no error handler present.
