In PharoDev-1.3.-13173 While loading Moose there's a 'Transcript open' in loadDefault. This image's Transcript does not understand #open. It's preventing clear installation of moose. Best regards, CdAB

Re: [Pharo-project] out of memory - cog on windows

by Alain_Rastoul

Hi Tudor, Sad that it didn't help you :-(. You should contact Igor and see if he is still ok to play with your image, he may certainly be able to find something. I will try to find this too, because I experienced a similar problem loading an image saved with the vm I sent you (2G) in the standard vm (512M) after I've loaded data from odbc , the saved image was about 300 Mo and I had a memory error loading it with the standard vm. Unfortunatly I didn't keep this image, I reopend it with the 2G vm, found the hanging references and reduced it to 40M, but I think I could reproduce it. You can also send me your image (upload at at http://dl.free.fr with a notification email - see the web page) , I'll have a try with your image too. Cheers, Alain.

The correct phrasing would be: "Sorry I haven't found time to finish the rewrite I talked about, during which I discovered this (didn't compile to see if it would cause an issue for Cog though), but probably neglected to tell you. For the reasons LocalePlugin is inadequate for those primitives as mentioned in other mail, I doubt I'll find motivation to finish it rather than do other things later on either." So, thanks for taking the effort of updating from trunk, sorry I couldn't be of any help. Cheers, Henry
