Hi,

I noticed that garbage collection seems to stop working when

marksPerAlloc is set to 5.5 or greater, resulting in
endlessly growing 
memory consumption.

To reproduce, execute in the io interpreter (and be prepared
to abort 
with Ctrl-C):

Io> Collector setMarksPerAlloc(#N)
Io> loop(Object clone)

Where #N is the number you'd like to test. Then observe the
interpreters 
memory consumption. With values up to 5.499 the memory
consumption stays 
constant while with 5.5 or greater it rises until out of
memory.

I use todays git version (ultimate commit: 
938159ed568c8c295a1ec557333614276645ca9f) compiled on a
x86-32 PC with 
Ubuntu "feisty" installed.


Can anybody reproduce?

Jonas

Should be fixed quite quickly, but it does seem to be a bug. Thanks

for reporting it and trying it all out! SteveDekorte seems to have

found it and probably will fix it soon.
