How long?  Seconds, minutes, hours?  I've let it run for 10 minutes, and no crash yet...

When you get the lisp from svn, it includes a set of binaries.  These binaries are not always up-to-date with the source code, but they are sufficient to rebuild the lisp.

Please do (rebuild-ccl :full t) to pick up all the bug-fixes that have been checked in to the 1.4 release branch since its release.  (See http://trac.clozure.com/ccl/wiki/UpdatingFromSource).

This may or may not have anything to do with your bug, but we might as well eliminate the possibility.
