+.B \-\-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.

 This option disables the debugger, causing errors to print a backtrace
 and exit with status 1 instead -- which is a mode of operation better suited
 for batch processing. See the User Manual on \f(CRSB\-EXT:DISABLE\-DEBUGGER\fR for details.
