OK, I'm emailing address@hidden  I'll include my original program
at the end of this email, in case it goes to a wider distribution list...

I did that, and indeed _gst_invalidate_method_cache gets called; in fact,
it gets called a lot, seemingly after every completed statement, and three
times in a row sometimes.

I cut and pasted it too, just to make sure I wasn't mistyping anything,
and I got the erratic behavior.  One thing my setup might have different
from yours is that I haven't run "make install" yet, but seeing as how gst
runs almost everything correctly, that shouldn't seem to make a
difference.

As far as my exact setup goes: I'm running Debian testing/unstable on a
PIII laptop.  I downloaded GNU smalltalk 2.1.2, I configured the system
using
  ./configure --enable-gtk --enable-jit
and I've included the configuration output below.  If you're interested in
any of the versions of system libraries or things I have, I'll be happy to
supply them.  (If it would be easier, I could even give you a temporary
account on my laptop so you can ssh over and see what's up for yourself?)

Thanks; sorry about the problem being non-repro for you.

Original program:
        Object subclass: #Account
            instanceVariableNames: 'balance'
            classVariableNames: ''
            poolDictionaries: ''
            category: nil !
       !Account class methodsFor: 'instance creation'!
        new
            | r |
            r := super new.
            r init.
            ^r
        ! !
        !Account methodsFor: 'instance initialization'!
        init
            balance := 0
        ! !
        Smalltalk at: #a put: (Account new) !
        a printNl !                            "This line causes problems!"
        !Account methodsFor: 'printing'!
        printOn: stream
            super printOn: stream.
            stream nextPutAll: ' with balance: '.
            balance printOn: stream
        ! !
The tutorial then has you type:
        a printNl !
and expects the following result:
        an Account with balance: 0
but what is actually printed out is:
        an Account
However, if the first line "a printNl !" is removed (the one right after a
is created), then the behavior is as expected, printing out the balance.
