[plt-scheme] DrScheme3m Under V350.3

I have tested my inference engine code on both Windows XP and Linux and on
both systems it crashes DrScheme3m under V350.3.  It runs fine under V350
(both DrScheme and DrScheme3m) and also runs fine under DrScheme for V350.3.
Under Windows XP, it generally dies with the GC indicator icon on and gives
the following generic error.


MrEd-based application has encountered a problem and needs to close.  We are
sorry for the inconvenience.


For Linux (Ubuntu 6.06) the window and application just go away.  It is
almost immediate on starting the computation and the crash is 100%
repeatable.  I'm not sure what other information I can give you.  I can, of
course, send the code to anyone who wants to investigate the problem.


The code is strictly Scheme - there are no FFI packages and it is entirely
self contained (there are no requires at all).  The only unusual thing I can
think of is that it does do quite a bit of destructive list manipulations.
It is also prototype code and likely leaks some, but I can't see that that
is the problem since it does run outside of the V350.3 3m environment.


[Note that in earlier posts today I was saying in at least some places 305.3
when I meant 350.3.]
