The latest 'fix' to the problem of some dangerous becomes is happy (so
far as my tests can tell) with the previously fatal case of 'a
becomeForward: a' which is what your walkback looks like. Try it again
and in the debugger see if the object being becomed is the same on both
sides. If it is, then the _very_ latest VM ought to be ok with it. A
not-quite so latest one will fail in what looks suspiciously like this
manner.

I wrote a long and rather boring explanation of the problem(s) in this
are in the 'becomeForward makes corrupted objects' mantis bug report.
