hello,
I stumbled upon this:
1) open an image with Cog
2) open a Worspace, evaluate 0.0 closeTo: 0 -> true (so far, so good)
3) now evaluate (1.0 closeTo: 1) and: [0.0 closeTo: 0] -> false !
4) evaluate again 0.0 closeTo: 0 -> false !
5) save the image and quit.
6) reopen the image, start again at 2...
???

Hi Stéphane,
cannot reproduce in my 4.1 derived updated image
#('0.0 closeTo: 0' '(1.0 closeTo: 1) and: [0.0 closeTo: 0]' '0.0 closeTo: 0') collect: [:s| Compiler evaluate: s] #(true true true)

I get #(true false false) in the 4.1 image released as a all-in-one Cog zip for Windows by Andreas, on the 20th, which you can get at http://squeakvm.org/win32/experimental/CogSqueak4.1.zip

To be as comprehensive as possible in my report:
I get #(true true true) on that very image with a regular Squeak4.0.2 VM.
I get #(true false false) either with the Cog VM in the archive or with the newer VM Levente provided today, based on VMMaker-oscog.17.mcz

Hi Stéphane ,
moving to the VM list...
we need to be specific on platforms. I've tested on both Mac and Windows, but not yet on linux. These VMs I've built myself from the svn tree:
svn info Path: . URL: http://www.squeakvm.org/svn/squeak/branches/Cog Repository Root: http://www.squeakvm.org/svn/squeak Repository UUID: fa1542d4-bde8-0310-ad64-8ed1123d492a Revision: 2219 Node Kind: directory Schedule: normal Last Changed Author: eliot Last Changed Rev: 2219 Last Changed Date: 2010-06-25 14:32:53 -0700 (Fri, 25 Jun 2010)
The build version infos are: (Smalltalk getSystemAttribute: 1006), (String with: Character cr), (Smalltalk getSystemAttribute: 1007), (String with: Character cr), (Smalltalk getSystemAttribute: 1008)
'Mac OS X built on Jun 26 2010 08:21:33 Compiler: 4.2.1 (Apple Inc. build 5659) CoInterpreter VMMaker-oscog.17 uuid: b0ce2f1b-0e18-48d8-a490-4b8ca8476ec7 Jun 27 2010 SimpleStackBasedCogit VMMaker-oscog.16 uuid: f8b8c00f-be77-4358-a537-ac5dd4e27747 Jun 27 2010'
'Win32 built on Jun 27 2010 10:28:30 Compiler: 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) CoInterpreter VMMaker-oscog.17 uuid: b0ce2f1b-0e18-48d8-a490-4b8ca8476ec7 Jun 27 2010 SimpleStackBasedCogit VMMaker-oscog.16 uuid: f8b8c00f-be77-4358-a537-ac5dd4e27747 Jun 27 2010'
and for both Mac OS X & Win32 the results in a Squeak4.1 updated from trunk are #('0.0 closeTo: 0' '(1.0 closeTo: 1) and: [0.0 closeTo: 0]' '0.0 closeTo: 0') collect: [:s| Compiler evaluate: s] #(true true true)
What's your platform and build info?
cheers, Eliot

This image is missing the Cog floating point byte order fixes. I need to update it.

Doh! I should have suspected as much.
humble mumble, Eliot
