Repeatable VM crash

When playing with equality in a class hierarchy I have repeatable VM crash.
It is today Pharo VM 3.9-7 from Jenkins and Pharo3.

Am I using an out of date VM?

Crashdump enclosed

Re: Repeatable VM crash

Hi again,

I must add it occurs from a test or when comparing something like this
in the Workspace:

(CGDonator firstname: 'Eric' lastname: 'Dupont') = (CGParticipant
firstname: 'Eric' lastname: 'Dupont')

I get a false returned value printed in the Workspace, then VM crash.

Thanks

Re: Repeatable VM crash

Hi Hilaire,

can you try and concoct an image that crashes from start-up without operator intervention? What I mean is that if the expression that crashes is the one you give then in a workspace evaluate

Smalltalk snapshot: true andQuit: true.

(CGDonator firstname: 'Eric' lastname: 'Dupont') = (CGParticipant firstname: 'Eric' lastname: 'Dupont')

and then run the saved image. If it crashes then its really easy to debug because it will be repeatable. If one has to interact with the image debugging is much more difficult.

Re: Repeatable VM crash

yes, but the first step is to be sure you have the latest vm version :)

Re: Repeatable VM crash

I download the latest from jenkin? Build date in the crash log.
Am I missing something?

Hi Esteban,

plausibly the fix to the latest VM might fix your crash. You might test? Fingers crossed.

yes, tests now are finishing without crash!

now that we are ready yet, but almost there :)

different bugs. The 3164 VMs fix a 32-bit Spur bug. Your image is showing a bug in Cog that looks to be to do with the decompression primitive. I haven't had time to look at it deeply yet but can see it and should be able to fix it soon.

No. That bug got fixed recently. This is a bug in the custom huffman-ciding bitmap decompression routine (selector begins with "decompress") that's compiled to a primitive.

Hi,

It seems Stephan is seeing this bug again.

Eliot, is there a chance that the fix was not finally integrated or something?

Hi,

Eliot, is there a chance that the fix was not finally integrated or something?

vm build is at least 1 month old (spur one). Cog vm is at least 6 months old (yet some stuff has been integrated into it, but not much).

vm development is moving to spur branch so changes will be there (and not old cog branch) but to resume vm build we need to fix a bug in opal compiler (in spur context): https://pharo.fogbugz.com/f/cases/17251

So… probably, that bug fix is not present yet in the vm (I cannot be sure, but probably)
