+@item --disable-ldb
+Disable the low-level debugger. Only effective if SBCL is compiled
+with LDB.
+
+@item --lose-on-corruption
+There are some dangerous low level errors (for instance, control stack
+exhausted, memory fault) that (or whose handlers) can corrupt the
+image. By default SBCL prints a warning, then tries to continue and
+handle the error in Lisp, but this will not always work and SBCL may
+malfunction or even hang. With this option, upon encountering such an
+error SBCL will invoke ldb (if present and enabled) or else exit.
