Hi,
 I wanted to report a crash of the Mac Spur VM (32 and 64 bits) when doing the following on the Cuis 5.0, version 3064 image:

1) On a workspace write: [ 1 xxx ] value
2) evaluate it
3) when the debuggers opens, select the second context from the context debugger's list (that is, the context previous the top one, where the [ 1 xxx ] is)
4) press the "Create" button to create the method
5) select Integer
6) select "as yet unclassified"
7) here is where it crashes

It happens on the 64 and 32 bits VMs for the MAC (I did not try it with Linux neither Windows)
I'm using Cuis5.0-3064-spur-64.image and Cuis5.0-3064-spur.image (32 bits) (The latest version of Cuis solves this problem selecting automatically the top of the context list when creating the method)
The same sequence on a stack VM shows the "emergency evaluator" and does not crashes
Attached is the dump of the 64 bits VM.

Hernan.

Hi Hernan,

    I just tried to reproduce in Squeak and there it does not crash.  So perhaps there's some preparation necessary that Cuis does not do?  I don't have time to look at the Cuis image right now.  Perhaps remind me early next week?

My Squeak crashes doing this, both in 32 and 64 bits, in primitiveSlotAt/mustMapMachineCodePCcontext. 

In step 4 of Hernan's instructions I executed "self createMethod" in an inspector on the debugger (because we don't have the "create" button anymore in Squeak apparently).

Here's the 64 bit crash:

4   libsystem_platform.dylib       0x00007fff8615552a _sigtramp + 26
5   ???                           000000000000000000 0 + 0

9   org.squeak.Squeak$(VM_MONIKER) 0x000000010c7c0891 interpret + 631

And this is the 32 bit one:

Hi Bert! thank you for trying it with Squeak.
Eliot, I'm attaching a squeak change set you can file in that shows the create button on the debugger and therefore you will be able to reproduce the same sequence on Squeak.
I hope this help!

Hernan.

The crash *only* happens when the message is inside a block, and in the debugger the second context is selected. In the pre-debug window it works fine, if any other context is selected it's fine, and without the block it's fine, too.

Probably lots of things different at this level that just side-steps
the problem,
but just for additional info, following Hernan's steps does crash Pharo.
