Hi Eliot,

I use MongoDB and the Problem occurs when the user clicks within its web browser.
I don't use Native Boost etc. Only lots of Pharo features like Artifact, Zinc etc.
Yes, sure, I can try with other vms.
I can try to force the bug with a smalltalk script instead of clicking within the application but the need of mongo db remains.
I will think about how to create a straight forward reproducible case to you. 
You can send the vm to me I will test it.

Regards
Sabine

Hi Sabine,

    you have a reproducible case.  Does the image require any surrounding infrastructure to reproduce the problem or is it self-contained?  Do you use any special Pharo facilities such as Native Boost?  If the problem is self-contained would you be willing to try one of my recent VMs and see if it crashes there-on?  If it does, I'd like either you to run the system using an assert-enabled VM and/or you to send me the image and changes and let me take a look at the crash.  An assert-enabled VM is one full of run-time consistency checks and it tends to move the point of detection in a bug earlier, before things are so messed up that the VM actually crashes.  It is significantly slower than the production VM, which is why its only used to debug/verify.

Ideally a reproducible case crashes from start-up without user intervention.  This makes it more straight-forward to debug. If you can package the crash as a doit that starts with a snapshot that's ideal.  Something like

    Smalltalk image snapshot: true andQuit: true.
    self doSomethingThatCrashes

This can be run from inside an inspector on a live instance if necessary, avoiding needing to initialize the application, etc.

Hi Esteban,

I downloaded the Pharo vm with file date 16.7.2015 and startet it with a
pharo 4 image
(curl get.pharo.org/vmLatest50 | bash).
The problem remains - also with the newer vm.
I reproduced it twice, please see the stack dump below.
Can you see in the dump below that I used the right vm?
Is this helpful?

Now I try to create a reproducible case.

regards
Sabine
