I'm trying to run CCL on an Acer Iconia A500. That's an Android tablet but I run Debian (Squeeze) in a chroot environment. CCL starts but backtraces don't seem to work:

Is this a known problem of the ARM port? Has it something to do with the chroot tricks? Perhaps because /proc doesn't not working quite correclty with chroot?

Redefining a class does not work properly when the first def contains :default-initargs, but the second def does not. What happens is that use of the second def still has the default initiarg.

? (defclass foo () ((x :accessor x :initarg :x)) (:default-initargs :x 2))

? (describe (make-instance 'foo))

#<FOO #x302093A3C44D>
Class: #<STANDARD-CLASS FOO>
Wrapper: #<CCL::CLASS-WRAPPER FOO #x302093A3E25D>
Instance slots
X: 2

? (defclass foo () ((x :accessor x :initarg :x)))

? (describe (make-instance 'foo))

#<FOO #x302093A3C44D>
Class: #<STANDARD-CLASS FOO>
Wrapper: #<CCL::CLASS-WRAPPER FOO #x302093A3E25D>

X: 2

On Win32 (Windows XP SP3), it seems CCL r14647 and later cause exceptions at the time of a disconnection.

This is the quote from *inferior-lisp* buffer:

Can I ignore it?
