+;;; * OpenBSD address space changes for W^X as well as malloc
+;;; randomization made the old addresses unsafe. The only range
+;;; that is really safe is between the end of the text segment (it
+;;; starts at #x3C000000) and #x7C000000. However if the -Z linker
+;;; option is used then the safe range is (probably) #x00001000 to
+;;; #x48048000, with the text and data segments at #x08048000.
