Thanks.

I have switched the Moose job back to using the latest image. Let’s see how it works.

Cheers, Doru

Hi Eliot,

Thanks to take care of this issue!

Pavel opened a bug issue here: https://pharo.fogbugz.com/f/cases/19785/Athens-crashes-the-VM . You need the latest Pharo image and VM and it crashes under Linux (32-bit) and OSX (El Captain, 32-bit VM). And I personally tried with Windows7 and the bug happens too.

To reproduce: Morph new testAthensRender

An extract of the opened issue:

Edited by Pavel Krivanek 02/03/2017 (Today) 16:10

An empty surface crashes it too: surf := AthensCairoSurface extent: Display extent. Display getCanvas drawImage: surf asForm at: 0@0

The problem is in the method AthensCairoSurface>>#asForm where the previous slice started to add 1 to surface heigth

Well, I tried to revert AthensCairoSurface>>#asForm which fixes this particular case but Roassal still crashes on copyBits

Cheers,

Vincent

Hi Vincent,

first, apologies for the inconvenience, second, thanks!  I badly need

reproducible failure cases to get the remaining bugs out of the compactor and you have just provided me with one. Can you send me the information I need to reproduce the build? What platforms does it fall on?

Hi,

The latest builds of the Moose6.1 image are failing due to a segmentation fault.

Here is the link to the last build: https://ci.inria.fr/moose/job/moose-6.1/550/console

How can we fix this?
