[Chicken-hackers] 4.7.5 modified -> 4.8.2: heap full while resizing is back

[Jörg F . Wittenberger]

At 21 Oct 2011 I proposed some changes, which apparently have made it 
half-way into the chicken core so far. See 
http://lists.nongnu.org/archive/html/chicken-hackers/2011-10/msg00084.html

At 19 Jun 2012 in
http://lists.nongnu.org/archive/html/chicken-hackers/2012-06/msg00051.html
I mentioned some more changes I made, which eventually made those
"heap full while resizing" go away.  (I kept the mutation stack
under a limit.)

Now with my compile upgrade I somehow killed this change (since
parts of it apparently went into the core).

However the problem is back.  I can't run my code for any reasonable
amount of time.  While it runs almost forever with the modified
4.7.5 code within about 128MB of memory, it grows beyond any reasonable
size in seconds again.

I'll try to bring my changes back in locally.  But I'll need help
to prepare diffs for integration.  Who's interested?

Best Regards

/Jörg
