I have also entered this on Mantis as #0000845.

The problem appears to be related to one of the KCP changes, so perhaps someone
on the KCP team could take a look.

The bug appears to have been introduced by a change to ClassBuilder>>recompile:from:to:mutate:

The change record is stamped: 'NS 1/21/2004 09:53 ClassBuilder recompile:from:to:mutate:'

It was introduced into the image as part of the SystemChangeHooks change set:

'From Squeak3.7alpha of ''11 September 2003'' [latest update: #5623] on 28 January 2004 at 11:12:37 am'!
