Hi, when I have one of my multi-touch programs open, Pharo occasionally (read once every few days) just crashes. Ubuntu mentions a failure to report to Ubuntu on the pharovm but I'm not sure how to understand that failure. I thought it might be one of two things: (1) some sort of problem with Athens rendering or (2) some sort of problem with the multi-touch events. Those are really the only things that separate when I'm developing and when I'm testing. It never crashes when I'm developing, which is a much larger percentage of the time. Recently, the crash happened when I was not touching the display. That meant that there would not have been any touch events to process, nor would an Athens render happen. Strange. I'm not sure how to proceed. I've turned off the multi-touch support for the time being to see if it still happens. If so, that would probably exonerate the multi-touch code. Does anyone else have rare random unexplained crashes happening while using Athens? Is there anything I could do to better diagnose the problem. It's fiendish as it happens so rarely and there is no replicable action that causes it to happen. Cheers, Jeff -- Jochen "Jeff" Rick, Ph.D. http://www.je77.com/ Skype ID: jochenrick

i fixed recently this one:

Cool! I am using SVG files so there might be some unicode data being sent to Cairo buffer. On the other hand, my crash happens randomly, rather than as a result of a specific repeatable action. It sounds like this would be more along the lines of a repeatable sequence. Anyway, I'll update the code and see if it helps. Again, this problem is difficult to diagnose as the crash only happens every other day. Even if it doesn't happen all week, it doesn't mean that that was the problem. For instance, there have been no crashes today, so it makes me think that the multi-touch support, rather than Athens, is the culprit.

Hi, PharoDebug.log and crash,dmp could be helpful also, to understand what happens. Esteban On 09 Apr 2014, at 15:01, J.F. Rick <self@je77.com> wrote:

And compiling an assert VM and running it from the command line to see any assert-fails. It could be a VM bug.
