In sbcl-0.8.13, all backtraces from errors caused by internal errors
on the alpha seem to have a "bogus stack frame".
-347: FUNCALL forms and compiler-macros
- (reported by Johan Bockgård on #lisp)
- The example
- (funcall (compiler-macro-function 'square) '(funcall #'square x) nil)
- => (EXPT X 2)
- from CLHS entry for DEFINE-COMPILER-MACRO fails in 0.8.13.41 with an
- error. Fixed in CMUCL 19a.
+348:
+ Structure slot setters do not preserve evaluation order:
+
+ (defstruct foo (x))
+
+ (let ((i (eval '-2))
+ (x (make-foo)))
+ (funcall #'(setf foo-x)
+ (incf i)
+ (aref (vector x) (incf i)))
+ (foo-x x))
+ => error
+
+349: PPRINT-INDENT rounding implementation decisions
+ At present, pprint-indent (and indeed the whole pretty printer)
+ more-or-less assumes that it's using a monospace font. That's
+ probably not too silly an assumption, but one piece of information
+ the current implementation loses is from requests to indent by a
+ non-integral amount. As of sbcl-0.8.15.9, the system silently
+ truncates the indentation to an integer at the point of request, but
+ maybe the non-integral value should be propagated through the
+ pprinter and only truncated at output? (So that indenting by 1/2
+ then 3/2 would indent by two spaces, not one?)
