Your program looks OK to me.  There is a known stack overflow problem
on some OSs, when just trying to load boot-9.scm, and when libguile is
compiled without much optimization.  What OS are you running on?
Also, if you could manage to test the same program with the latest
release (1.8.5), please do that and let us know the result.
