@@ -1792,3 +1792,57 @@ WORKAROUND:
   Test :NAN-COMPARISONS in float.pure.lisp fails on x86-64, and has been
   disabled on those platforms. Since x86 does not exhibit any problems
   the problem is probably with the new FP implementation.

+413: type-errors in ROOM
+
+  (defvar *a* (make-array (expt 2 27)))
+  (room)
+
+  Causes a type-error on 32bit SBCL, as various byte-counts in ROOM
+  implementation overrun fixnums. 
+
+  This was fixed in 1.0.4.89, but the patch was reverted as it caused
+  ROOM to cons sufficiently to make running it in a loop deadly on
+  GENCGC: newly allocated objects survived to generation 1, where next
+  call to ROOM would see them, and allocate even more...
+
+  Reported by Faré Rideau on sbcl-devel.

+414: strange DISASSEMBLE warning
+
+  Compiling and disassembling 
+
+   (defun disassemble-source-form-bug (x y z)
+     (declare (optimize debug))
+     (list x y z))
+
+  Gives
+
+   WARNING: bogus form-number in form!  The source file has probably 
+   been changed too much to cope with.
+
+415: Issues creating large arrays on x86-64/Linux and x86/Darwin
+
+   (make-array (1- array-dimension-limit))
+
+   causes a GC invariant violation on x86-64/Linux, and
+   an unhandled SIGILL on x86/Darwin.
+
+416: backtrace confusion
+
+  (defun foo (x)
+    (let ((v "foo"))
+      (flet ((bar (z)
+               (oops v z)
+               (oops z v)))
+        (bar x)
+        (bar v))))
+  (foo 13)
+
+  gives the correct error, but the backtrace shows 
+    1: (SB-KERNEL:FDEFINITION-OBJECT 13 NIL)
+  as the second frame.
