Hi, what is wrong with this code: ----- cnt := 5000000. s := ' jasdfh afhahkjasdf asdf sd'. d := Dictionary new: cnt. 1 to: cnt do: [ :i | d at: i put: (i asString, s). (i \ 50000 = 0) ifTrue: [ Transcript show: i; cr. ]. ]. d size. -----
Squeak (latest 3.9) hangs randomly after 600 000 - 1 000 000 iterations (about 129MB of RAM [2GB] used before hang).
hang = white squeak window, no interaction possible, 100% of cpu usage
Thanks for suggestions, pf
Hi Petr,
it just passed 1 250 000 here, without the symptoms you describe, on a 1GB WinXP notebook.
What platform are you using?

P.S. I always declare temps explicitly in a workspace, I don't like the possible surprise and also because I want to see the temps when I interrupt the DoIt with alt-.

Hi Petr,
hm, I think that I've seen that, have a look at
- http://bugs.impara.de/view.php?id=4709
Find the word "workaround" on that page. Perhaps this helps you, too.

Thanks for this workaround - it works now.
But highest value for -memory parameter is 880MB (on my Ubuntu Linux). If I try greater value than 880MB, squeak falls down with message: "bad address: negative".

Petr,
yes, there seems to be a limit <= 1GB in the 32bit VM's. It is perhaps possible to bypass the problem by using the -mmap argument but I have no experience with that.
Perhaps you find a more recent VM executable which fits:

IIRC > 1GB of memory is addressed in the 64bit VM's.
