This happens using the Pharo dev image 1.1.1

It seems to be related to the VM. To reproduce, just open a browser and save and quit. Then opening the image with Cog r2344 or r2345 will result in this error - it seems to be happening in the startup process. If you debug it, the code that apparently causes the problem actually works fine when manually invoked. Earlier versions of Cog don't have this problem - r2316 works fine. I'm using the standard 1.1.1 image on Linux (Omnibrowser is OB-Standard-lr.479) Regards, Stuart On Wed, Jan 12, 2011 at 3:06 AM, Pat Maddox <patmaddox@me.com> wrote:

Thanks pat for the report.

Now could you let us know if you loaded OB or if you used the public 1.1.1 oneclick?

I opened up an OmniBrowser and scrolled to the very bottom.  Then I clicked on my package name, and then a class name.

I'd still appreciate a clear description of how to reproduce (including OS etc) Fetching the context from a large email with a backtrace in it etc is not one of my strong points. On Wed, Jan 12, 2011 at 5:08 AM, Carla F. Griggio <carla.griggio@gmail.com>wrote:

Yes, it happens after save and quit! And I use Cog VM.

Great that you could reproduce, I didn't know what was causing it.

It seems to be related to the VM. To reproduce, just open a browser and save and quit. Then opening the image with Cog r2344 or r2345 will result in this error - it seems to be happening in the startup process. If you debug it, the code that apparently causes the problem actually works fine when manually invoked.

Earlier versions of Cog don't have this problem - r2316 works fine. I'm using the standard 1.1.1 image on Linux (Omnibrowser is OB-Standard-lr.479)

Thanks pat for the report.

Now could you let us know if you loaded OB or if you used the public 1.1.1 oneclick?

I opened up an OmniBrowser and scrolled to the very bottom. Then I clicked on my package name, and then a class name.

Ignore me. I'm deluded. The below should of course produce an error. Sorry for the noise. best Eliot On Wed, Jan 12, 2011 at 3:52 PM, Eliot Miranda <eliot.miranda@gmail.com>wrote:

Hi All,

I think I've found the reproducible case for the MessageNotUnderstood: LargePositiveInteger>>pixelValueForDepth: bug in the StackToRegisterMappingCogit. The symptom may be that the register arguments get shuffled incorrectly through an inline send miss. Here's an example that produces an MNU every time:

| s a ca | s := #(1 -1). a := Array new: 2. ca := ColorArray new: 2. a replaceFrom: 1 to: 2 with: s. ca replaceFrom: 1 to: 2 with: s.

I'll try and look at this this evening.

It seems to be related to the VM. To reproduce, just open a browser and save and quit. Then opening the image with Cog r2344 or r2345 will result in this error - it seems to be happening in the startup process. If you debug it, the code that apparently causes the problem actually works fine when manually invoked.

Earlier versions of Cog don't have this problem - r2316 works fine. I'm using the standard 1.1.1 image on Linux (Omnibrowser is OB-Standard-lr.479)

Thanks pat for the report.

Now could you let us know if you loaded OB or if you used the public 1.1.1 oneclick?
