I have added an 'extended random regression' feature to
the gcl ansi-tests suite. This feature runs runs only
the tests that are known to pass in the build, but
reruns them repeatedly, in random order, until
something breaks.

ERR found a weird bug in clisp (cvs head, 23 April
2005) involving generic functions, nconc method
combination, and defclass. The attached file causes
this error when it is loaded into clisp:

*** - SPECIALIZER-DIRECT-GENERIC-FUNCTIONS: Some
methods have been removed from their generic function,
but the list in the #<BUILT-IN-CLASS T>
specializer was not updated.

    Bruno, this is CLOS/MOP - could you please look at it?
