Bonjour,
This is only a guess, but it looks like some kind of problem loading image segments from disk. Try getting rid of the sm cache directory, and maybe it will work.

It looks like the same problem I occasionally get because the squeak object memory wraps over the 2Gb line; a small part of the segment loading prim goes bad if the addresses seem to be -ve int values. I'm sure we discussed this on-list some time ago but I can't actually find relevant mails right now. It is quite remarkable how few problems are caused by this effect.

Ah, yes, that's probably it. If I recall, the problem showed up for people running the newer Linux 2.6 kernels (maybe only on 64 bit machines? I'm not sure). If I remember right, I think that it was possible to work around the problem by forcing the VM to use a fixed memory allocation, something like "squeak -memory 40m myimage". I don't happen to have a Linux 2.6 system or a 64 bit machine to confirm this, but it's worth trying the " -memory" option to see if it helps.
Damien, essayez ceci:
$ squeak -memory 40m squeak.image
Dave
Not simply a Linux problem - if this is the ImageSegment issue I think you guys are referring to (apologies if not) then the problem appeared under OpenBSD 3.5 too; code sharing between L2.6 and OBSD3.5 kernels is of course non-existent.
But yeah, the quick-'n'-dirty hack is to avoid dynamic allocation by specifying a fixed heap, iirc. Goran and I submitted a few messages reporting such problems in July, with regards to SM update problems, based around ImageSegment negative pointers.
Goran's post: http://lists.squeakfoundation.org/pipermail/squeak-dev/2004-July/ 079498.html Mine: http://lists.squeakfoundation.org/pipermail/squeak-dev/2004-July/ 079505.html
Hope that helps.

I think that your system is trying to start Squeak with a script file. Perhaps you did this:
$ squeak -memory 40m squeak.image script => evaluate "script" on startup => BOOM
Or perhaps this:
$ squeak -memory 40m squeak.* => squeak memory 40m squeak.image squeak.something => evavluate "squeak.something" => BOOM
Try to run Squeak with the exact name of the image file.
Essayez d'employer le nom exact "squeak.image", pas "squeak*".

Oh, well ... I'm sorry it did not work. Perhaps someone else has an idea? See previous email from Damien for the debug log.
The original problem seemed to be related to loading image segments, so I had suggested running with "-memory 40m" to restrict memory ranges. This apparently got us by the original problem, but now Damien is seeing a problem (unrelated???) that looked to me like it might be due to Squeak trying to read a startup script file with binary data in it. No joy, and I'm out of ideas.
Reply in French and/or simple English if possible.

I can give one of you an access to my computer through ssh with X forwarded. I can give an access through vnc too, but I need to learn how to configure it.

Hi Damien!
I would have responded earlier if I hadn't been away in China. I am the SqueakMap "guy".

Nobody is interested by this connection to test the bug with squeakMap ?
Well, I have looked over your debug.log and this problem is not related to SM. It seems that Squeak is trying to install a script file that normally is given on the command line after the image name.
But you clearly stated that the last thing on the command line was the image name "squeak.image". So this is a bit baffling. I run 3.7-b5 on 2.6.8 and do not have this issue.
If your image is named "squeak.image" I think you don't need to give it on the command line. Does it work without it?

I run 3.7-b5 on 2.6.8 and do not have this issue.
There is a person who has a problem with your kernel and Squeak. Please reade the post "kernel, Squeak and memory" (08/27/2004 by Jan B. Krejci). Yesterday, he tells me that he has to boot another kernel to use squeak.
Thanks
